+      <title>Serial Peripheral Interface (SPI)</title>
+  <para>
+	SPI is the "Serial Peripheral Interface", widely used with
+	embedded systems because it is a simple and efficient
+	interface:  basically a multiplexed shift register.
+	Its three signal wires hold a clock (SCK, often in the range
+	of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
+	a "Master In, Slave Out" (MISO) data line.
+	SPI is a full duplex protocol; for each bit shifted out the
+	MOSI line (one per clock) another is shifted in on the MISO line.
+	Those bits are assembled into words of various sizes on the
+	way to and from system memory.
+	An additional chipselect line is usually active-low (nCS);
+	four signals are normally used for each peripheral, plus
+	sometimes an interrupt.
+  </para>
+  <para>
+	The SPI bus facilities listed here provide a generalized
+	interface to declare SPI busses and devices, manage them
+	according to the standard Linux driver model, and perform
+	input/output operations.
+	At this time, only "master" side interfaces are supported,
+	where Linux talks to SPI peripherals and does not implement
+	such a peripheral itself.
+	(Interfaces to support implementing SPI slaves would
+	necessarily look different.)
+  </para>
+  <para>
+	The programming interface is structured around two kinds of driver,
+	and two kinds of device.
+	A "Controller Driver" abstracts the controller hardware, which may
+	be as simple as a set of GPIO pins or as complex as a pair of FIFOs
+	connected to dual DMA engines on the other side of the SPI shift
+	register (maximizing throughput).  Such drivers bridge between
+	whatever bus they sit on (often the platform bus) and SPI, and
+	expose the SPI side of their device as a
+	<structname>struct spi_master</structname>.
+	SPI devices are children of that master, represented as a
+	<structname>struct spi_device</structname> and manufactured from
+	<structname>struct spi_board_info</structname> descriptors which
+	are usually provided by board-specific initialization code.
+	A <structname>struct spi_driver</structname> is called a
+	"Protocol Driver", and is bound to a spi_device using normal
+	driver model calls.
+  </para>
+  <para>
+	The I/O model is a set of queued messages.  Protocol drivers
+	submit one or more <structname>struct spi_message</structname>
+	objects, which are processed and completed asynchronously.
+	(There are synchronous wrappers, however.)  Messages are
+	built from one or more <structname>struct spi_transfer</structname>
+	objects, each of which wraps a full duplex SPI transfer.
+	A variety of protocol tweaking options are needed, because
+	different chips adopt very different policies for how they
+	use the bits transferred with SPI.

+		How to mount the root file system in uClinux/Blackfin
+		-----------------------------------------------------
+
+1	Mounting EXT3 File system.
+	------------------------
+
+	Creating an EXT3 File system for uClinux/Blackfin:
+
+
+Please follow the steps to form the EXT3 File system and mount the same as root
+file system.
+
+a	Make an ext3 file system as large as you want the final root file
+	system.
+
+		mkfs.ext3  /dev/ram0 <your-rootfs-size-in-1k-blocks>
+
+b	Mount this Empty file system on a free directory as:
+
+		mount -t ext3 /dev/ram0  ./test
+			where ./test is the empty directory.
+
+c	Copy your root fs directory that you have so carefully made over.
+
+		cp -af  /tmp/my_final_rootfs_files/* ./test
+
+		(For ex: cp -af uClinux-dist/romfs/* ./test)
+
+d	If you have done everything right till now you should be able to see
+	the required "root" dir's (that's etc, root, bin, lib, sbin...)
+
+e	Now unmount the file system
+
+		umount  ./test
+
+f	Create the root file system image.
+
+		dd if=/dev/ram0 bs=1k count=<your-rootfs-size-in-1k-blocks> \
+		> ext3fs.img
+
+
+Now you have to tell the kernel that will be mounting this file system as
+rootfs.
+So do a make menuconfig under kernel and select the Ext3 journaling file system
+support under File system --> submenu.
+
+
+2.	Mounting EXT2 File system.
+	-------------------------
+
+By default the ext2 file system image will be created if you invoke make from
+the top uClinux-dist directory.
+
+
+3.	Mounting CRAMFS File System
+	----------------------------
+
+To create a CRAMFS file system image execute the command
+
+	mkfs.cramfs ./test cramfs.img
+
+	where ./test is the target directory.
+
+
+4.	Mounting ROMFS File System
+	--------------------------
+
+To create a ROMFS file system image execute the command
+
+	genromfs -v -V "ROMdisk" -f romfs.img -d ./test
+
+	where ./test is the target directory
+
+
+5.	Mounting the JFFS2 Filesystem
+	-----------------------------
+
+To create a compressed JFFS filesystem (JFFS2), please execute the command
+
+	mkfs.jffs2 -d ./test -o jffs2.img
+
+	where ./test is the target directory.
+
+However, please make sure the following is in your kernel config.
+
+/*
+ * RAM/ROM/Flash chip drivers
+ */
+#define CONFIG_MTD_CFI 1
+#define CONFIG_MTD_ROM 1
+/*
+ * Mapping drivers for chip access
+ */
+#define CONFIG_MTD_COMPLEX_MAPPINGS 1
+#define CONFIG_MTD_BF533 1
+#undef CONFIG_MTD_UCLINUX
+
+Through the u-boot boot loader, use the jffs2.img in the corresponding
+partition made in linux-2.6.x/drivers/mtd/maps/bf533_flash.c.
+
+NOTE - 	Currently the Flash driver is available only for EZKIT. Watch out for a
+	STAMP driver soon.
+
+
+6. 	Mounting the NFS File system
+	-----------------------------
+
+	For mounting the NFS please do the following in the kernel config.
+
+	In Networking Support --> Networking options --> TCP/IP networking -->
+		IP: kernel level autoconfiguration
+
+	Enable BOOTP Support.
+
+	In Kernel hacking --> Compiled-in kernel boot parameter add the following
+
+		root=/dev/nfs rw ip=bootp
+
+	In File system --> Network File system, Enable
+
+		NFS file system support --> NFSv3 client support
+		Root File system on NFS
+
+	in uClibc menuconfig, do the following
+	In Networking Support
+		enable Remote Procedure Call (RPC) support
+			Full RPC Support
+
+	On the Host side, ensure that /etc/dhcpd.conf looks something like this
+
+		ddns-update-style ad-hoc;
+		allow bootp;
+		subnet 10.100.4.0 netmask 255.255.255.0 {
+		default-lease-time 122209600;
+		max-lease-time 31557600;
+		group {
+			host bf533 {
+				hardware ethernet 00:CF:52:49:C3:01;
+				fixed-address 10.100.4.50;
+				option root-path "/home/nfsmount";
+			}
+		}
+
+	ensure that /etc/exports looks something like this
+		/home/nfsmount *(rw,no_root_squash,no_all_squash)
+
+	 run the following commands as root (may differ depending on your
+	 distribution) :
+		-  service nfs start
+		-  service portmap start
+		-  service dhcpd start
+		-  /usr/sbin/exportfs

+
+How to lock your code in cache in uClinux/blackfin
+--------------------------------------------------
+
+There are only a few steps required to lock your code into the cache.
+Currently you can lock the code by Way.
+
+Below are the interface provided for locking the cache.
+
+
+1. cache_grab_lock(int Ways);
+
+This function grab the lock for locking your code into the cache specified
+by Ways.
+
+
+2. cache_lock(int Ways);
+
+This function should be called after your critical code has been executed.
+Once the critical code exits, the code is now loaded into the cache. This
+function locks the code into the cache.
+
+
+So, the example sequence will be:
+
+	cache_grab_lock(WAY0_L);	/* Grab the lock */
+
+	critical_code();		/* Execute the code of interest */
+
+	cache_lock(WAY0_L);		/* Lock the cache */
+
+Where WAY0_L signifies WAY0 locking.

+Deferred IO
+-----------
+
+Deferred IO is a way to delay and repurpose IO. It uses host memory as a
+buffer and the MMU pagefault as a pretrigger for when to perform the device
+IO. The following example may be a useful explaination of how one such setup
+works:
+
+- userspace app like Xfbdev mmaps framebuffer
+- deferred IO and driver sets up nopage and page_mkwrite handlers
+- userspace app tries to write to mmaped vaddress
+- we get pagefault and reach nopage handler
+- nopage handler finds and returns physical page
+- we get page_mkwrite where we add this page to a list
+- schedule a workqueue task to be run after a delay
+- app continues writing to that page with no additional cost. this is
+  the key benefit.
+- the workqueue task comes in and mkcleans the pages on the list, then
+ completes the work associated with updating the framebuffer. this is
+  the real work talking to the device.
+- app tries to write to the address (that has now been mkcleaned)
+- get pagefault and the above sequence occurs again
+
+As can be seen from above, one benefit is roughly to allow bursty framebuffer
+writes to occur at minimum cost. Then after some time when hopefully things
+have gone quiet, we go and really update the framebuffer which would be
+a relatively more expensive operation.
+
+For some types of nonvolatile high latency displays, the desired image is
+the final image rather than the intermediate stages which is why it's okay
+to not update for each write that is occuring.
+
+It may be the case that this is useful in other scenarios as well. Paul Mundt
+has mentioned a case where it is beneficial to use the page count to decide
+whether to coalesce and issue SG DMA or to do memory bursts.
+
+Another one may be if one has a device framebuffer that is in an usual format,
+say diagonally shifting RGB, this may then be a mechanism for you to allow
+apps to pretend to have a normal framebuffer but reswizzle for the device
+framebuffer at vsync time based on the touched pagelist.
+
+How to use it: (for applications)
+---------------------------------
+No changes needed. mmap the framebuffer like normal and just use it.
+
+How to use it: (for fbdev drivers)
+----------------------------------
+The following example may be helpful.
+
+1. Setup your structure. Eg:
+
+static struct fb_deferred_io hecubafb_defio = {
+	.delay		= HZ,
+	.deferred_io	= hecubafb_dpy_deferred_io,
+};
+
+The delay is the minimum delay between when the page_mkwrite trigger occurs
+and when the deferred_io callback is called. The deferred_io callback is
+explained below.
+
+2. Setup your deferred IO callback. Eg:
+static void hecubafb_dpy_deferred_io(struct fb_info *info,
+				struct list_head *pagelist)
+
+The deferred_io callback is where you would perform all your IO to the display
+device. You receive the pagelist which is the list of pages that were written
+to during the delay. You must not modify this list. This callback is called
+from a workqueue.
+
+3. Call init
+	info->fbdefio = &hecubafb_defio;
+	fb_deferred_io_init(info);
+
+4. Call cleanup
+	fb_deferred_io_cleanup(info);

+Description
+-----------
+
+This driver permits reading temperature sensor embedded inside Intel Core CPU.
+Temperature is measured in degrees Celsius and measurement resolution is
+1 degree C. Valid temperatures are from 0 to TjMax degrees C, because
+the actual value of temperature register is in fact a delta from TjMax.
+
+Temperature known as TjMax is the maximum junction temperature of processor.
+Intel defines this temperature as 85C or 100C. At this temperature, protection
+mechanism will perform actions to forcibly cool down the processor. Alarm
+may be raised, if the temperature grows enough (more than TjMax) to trigger
+the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
+
+temp1_input	 - Core temperature (in millidegrees Celsius).
+temp1_crit	 - Maximum junction temperature  (in millidegrees Celsius).
+temp1_crit_alarm - Set when Out-of-spec bit is set, never clears.
+		   Correct CPU operation is no longer guaranteed.
+temp1_label	 - Contains string "Core X", where X is processor
+		   number.
+
+The TjMax temperature is set to 85 degrees C if undocumented model specific
+register (UMSR) 0xee has bit 30 set. If not the TjMax is 100 degrees C as
+(sometimes) documented in processor datasheet.

+fan3_input	ro	"
+fan4_input	ro	"
+fan1_target	rw	desired fan speed in RPM (closed loop mode only)
+pwm1_enable	rw	regulator mode, 0=full on, 1=open loop, 2=closed loop
+pwm1		rw	relative speed (0-255), 255=max. speed.
+			Used in open loop mode only.
+fan1_div	rw	sets the speed range the inputs can handle. Legal
+			values are 1, 2, 4, and 8. Use lower values for
+			faster fans.
+
+Module parameters
+-----------------
+
+If your board has a BIOS that initializes the MAX6650/6651 correctly, you can
+simply load your module without parameters. It won't touch the configuration
+registers then. If your board BIOS doesn't initialize the chip, or you want
+different settings, you can set the following parameters:
+
+voltage_12V: 5=5V fan, 12=12V fan, 0=don't change
+prescaler: Possible values are 1,2,4,8,16, or 0 for don't change
+clock: The clock frequency in Hz of the chip the driver should assume [254000]
+
+Please have a look at the MAX6650/6651 data sheet and make sure that you fully
+understand the meaning of these parameters before you attempt to change them.

+IPF Machine Check (MC) error inject tool
+========================================
+
+IPF Machine Check (MC) error inject tool is used to inject MC
+errors from Linux. The tool is a test bed for IPF MC work flow including
+hardware correctable error handling, OS recoverable error handling, MC
+event logging, etc.
+
+The tool includes two parts: a kernel driver and a user application
+sample. The driver provides interface to PAL to inject error
+and query error injection capabilities. The driver code is in
+arch/ia64/kernel/err_inject.c. The application sample (shown below)
+provides a combination of various errors and calls the driver's interface
+(sysfs interface) to inject errors or query error injection capabilities.
+
+The tool can be used to test Intel IPF machine MC handling capabilities.
+It's especially useful for people who can not access hardware MC injection
+tool to inject error. It's also very useful to integrate with other
+software test suits to do stressful testing on IPF.
+
+Below is a sample application as part of the whole tool. The sample
+can be used as a working test tool. Or it can be expanded to include
+more features. It also can be a integrated into a libary or other user
+application to have more thorough test.
+
+The sample application takes err.conf as error configuation input. Gcc
+compiles the code. After you install err_inject driver, you can run
+this sample application to inject errors.
+
+Errata: Itanium 2 Processors Specification Update lists some errata against
+the pal_mc_error_inject PAL procedure. The following err.conf has been tested
+on latest Montecito PAL.
+
+err.conf:
+
+#This is configuration file for err_inject_tool.
+#The format of the each line is:
+#cpu, loop, interval, err_type_info, err_struct_info, err_data_buffer
+#where
+#	cpu: logical cpu number the error will be inject in.
+#	loop: times the error will be injected.
+#	interval: In second. every so often one error is injected.
+#	err_type_info, err_struct_info: PAL parameters.
+#
+#Note: All values are hex w/o or w/ 0x prefix.
+
+
+#On cpu2, inject only total 0x10 errors, interval 5 seconds
+#corrected, data cache, hier-2, physical addr(assigned by tool code).
+#working on Montecito latest PAL.

+Debugging suspend and resume
+	(C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+1. Testing suspend to disk (STD)
+
+To verify that the STD works, you can try to suspend in the "reboot" mode:
+
+# echo reboot > /sys/power/disk
+# echo disk > /sys/power/state
+
+and the system should suspend, reboot, resume and get back to the command prompt
+where you have started the transition.  If that happens, the STD is most likely
+to work correctly, but you need to repeat the test at least a couple of times in
+a row for confidence.  This is necessary, because some problems only show up on
+a second attempt at suspending and resuming the system.  You should also test
+the "platform" and "shutdown" modes of suspend:
+
+# echo platform > /sys/power/disk
+# echo disk > /sys/power/state
+
+or
+
+# echo shutdown > /sys/power/disk
+# echo disk > /sys/power/state
+
+in which cases you will have to press the power button to make the system
+resume.  If that does not work, you will need to identify what goes wrong.
+
+a) Test mode of STD
+
+To verify if there are any drivers that cause problems you can run the STD
+in the test mode:
+
+# echo test > /sys/power/disk
+# echo disk > /sys/power/state
+
+in which case the system should freeze tasks, suspend devices, disable nonboot
+CPUs (if any), wait for 5 seconds, enable nonboot CPUs, resume devices, thaw
+tasks and return to your command prompt.  If that fails, most likely there is
+a driver that fails to either suspend or resume (in the latter case the system
+may hang or be unstable after the test, so please take that into consideration).
+To find this driver, you can carry out a binary search according to the rules:
+- if the test fails, unload a half of the drivers currently loaded and repeat
+(that would probably involve rebooting the system, so always note what drivers
+have been loaded before the test),
+- if the test succeeds, load a half of the drivers you have unloaded most
+recently and repeat.
+
+Once you have found the failing driver (there can be more than just one of
+them), you have to unload it every time before the STD transition.  In that case
+please make sure to report the problem with the driver.
+
+It is also possible that a cycle can still fail after you have unloaded
+all modules. In that case, you would want to look in your kernel configuration
+for the drivers that can be compiled as modules (testing again with them as
+modules), and possibly also try boot time options such as "noapic" or "noacpi".
+
+b) Testing minimal configuration
+
+If the test mode of STD works, you can boot the system with "init=/bin/bash"
+and attempt to suspend in the "reboot", "shutdown" and "platform" modes.  If
+that does not work, there probably is a problem with a driver statically
+compiled into the kernel and you can try to compile more drivers as modules,
+so that they can be tested individually.  Otherwise, there is a problem with a
+modular driver and you can find it by loading a half of the modules you normally
+use and binary searching in accordance with the algorithm:
+- if there are n modules loaded and the attempt to suspend and resume fails,
+unload n/2 of the modules and try again (that would probably involve rebooting
+the system),
+- if there are n modules loaded and the attempt to suspend and resume succeeds,
+load n/2 modules more and try again.
+
+Again, if you find the offending module(s), it(they) must be unloaded every time
+before the STD transition, and please report the problem with it(them).
+
+c) Advanced debugging
+
+In case the STD does not work on your system even in the minimal configuration
+and compiling more drivers as modules is not practical or some modules cannot
+be unloaded, you can use one of the more advanced debugging techniques to find
+the problem.  First, if there is a serial port in your box, you can set the
+CONFIG_DISABLE_CONSOLE_SUSPEND kernel configuration option and try to log kernel
+messages using the serial console.  This may provide you with some information
+about the reasons of the suspend (resume) failure.  Alternatively, it may be
+possible to use a FireWire port for debugging with firescope
+(ftp://ftp.firstfloor.org/pub/ak/firescope/).  On i386 it is also possible to
+use the PM_TRACE mechanism documented in Documentation/s2ram.txt .
+
+2. Testing suspend to RAM (STR)
+
+To verify that the STR works, it is generally more convenient to use the s2ram
+tool available from http://suspend.sf.net and documented at
+http://en.opensuse.org/s2ram .  However, before doing that it is recommended to
+carry out the procedure described in section 1.
+
+Assume you have resolved the problems with the STD and you have found some
+failing drivers.  These drivers are also likely to fail during the STR or
+during the resume, so it is better to unload them every time before the STR
+transition.  Now, you can follow the instructions at
+http://en.opensuse.org/s2ram to test the system, but if it does not work
+"out of the box", you may need to boot it with "init=/bin/bash" and test
+s2ram in the minimal configuration.  In that case, you may be able to search
+for failing drivers by following the procedure analogous to the one described in
+1b).  If you find some failing drivers, you will have to unload them every time
+before the STR transition (ie. before you run s2ram), and please report the
+problems with them.

+Testing suspend and resume support in device drivers
+	(C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+1. Preparing the test system
+
+Unfortunately, to effectively test the support for the system-wide suspend and
+resume transitions in a driver, it is necessary to suspend and resume a fully
+functional system with this driver loaded.  Moreover, that should be done
+several times, preferably several times in a row, and separately for the suspend
+to disk (STD) and the suspend to RAM (STR) transitions, because each of these
+cases involves different ordering of operations and different interactions with
+the machine's BIOS.
+
+Of course, for this purpose the test system has to be known to suspend and
+resume without the driver being tested.  Thus, if possible, you should first
+resolve all suspend/resume-related problems in the test system before you start
+testing the new driver.  Please see Documents/power/basic-pm-debugging.txt for
+more information about the debugging of suspend/resume functionality.
+
+2. Testing the driver
+
+Once you have resolved the suspend/resume-related problems with your test system
+without the new driver, you are ready to test it:
+
+a) Build the driver as a module, load it and try the STD in the test mode (see:
+Documents/power/basic-pm-debugging.txt, 1a)).
+
+b) Load the driver and attempt to suspend to disk in the "reboot", "shutdown"
+and "platform" modes (see: Documents/power/basic-pm-debugging.txt, 1).
+
+c) Compile the driver directly into the kernel and try the STD in the test mode.
+
+d) Attempt to suspend to disk with the driver compiled directly into the kernel
+in the "reboot", "shutdown" and "platform" modes.
+
+e) Attempt to suspend to RAM using the s2ram tool with the driver loaded (see:
+Documents/power/basic-pm-debugging.txt, 2).  As far as the STR tests are
+concerned, it should not matter whether or not the driver is built as a module.
+
+Each of the above tests should be repeated several times and the STD tests
+should be mixed with the STR tests.  If any of them fails, the driver cannot be
+regarded as suspend/resume-safe.

+   in userspace won't normally bring down any Linux system.
+
+ * Developing simple protocols used to talk to microcontrollers acting
+   as SPI slaves, which you may need to change quite often.
+
+Of course there are drivers that can never be written in userspace, because
+they need to access kernel interfaces (such as IRQ handlers or other layers
+of the driver stack) that are not accessible to userspace.
+
+
+DEVICE CREATION, DRIVER BINDING
+===============================
+The simplest way to arrange to use this driver is to just list it in the
+spi_board_info for a device as the driver it should use:  the "modalias"
+entry is "spidev", matching the name of the driver exposing this API.
+Set up the other device characteristics (bits per word, SPI clocking,
+chipselect polarity, etc) as usual, so you won't always need to override
+them later.
+
+(Sysfs also supports userspace driven binding/unbinding of drivers to
+devices.  That mechanism might be supported here in the future.)
+
+When you do that, the sysfs node for the SPI device will include a child
+device node with a "dev" attribute that will be understood by udev or mdev.
+(Larger systems will have "udev".  Smaller ones may configure "mdev" into
+busybox; it's less featureful, but often enough.)  For a SPI device with
+chipselect C on bus B, you should see:
+
+    /dev/spidevB.C ... character special device, major number 153 with
+	a dynamically chosen minor device number.  This is the node
+	that userspace programs will open, created by "udev" or "mdev".
+
+    /sys/devices/.../spiB.C ... as usual, the SPI device node will
+	be a child of its SPI master controller.
+
+    /sys/class/spidev/spidevB.C ... created when the "spidev" driver
+	binds to that device.  (Directory or symlink, based on whether
+	or not you enabled the "deprecated sysfs files" Kconfig option.)
+
+Do not try to manage the /dev character device special file nodes by hand.
+That's error prone, and you'd need to pay careful attention to system
+security issues; udev/mdev should already be configured securely.
+
+If you unbind the "spidev" driver from that device, those two "spidev" nodes
+(in sysfs and in /dev) should automatically be removed (respectively by the
+kernel and by udev/mdev).  You can unbind by removing the "spidev" driver
+module, which will affect all devices using this driver.  You can also unbind
+by having kernel code remove the SPI device, probably by removing the driver
+for its SPI controller (so its spi_master vanishes).
+
+Since this is a standard Linux device driver -- even though it just happens
+to expose a low level API to userspace -- it can be associated with any number
+of devices at a time.  Just provide one spi_board_info record for each such
+SPI device, and you'll get a /dev device node for each device.
+
+
+BASIC CHARACTER DEVICE API
+==========================
+Normal open() and close() operations on /dev/spidevB.D files work as you
+would expect.
+
+Standard read() and write() operations are obviously only half-duplex, and
+the chipselect is deactivated between those operations.  Full-duplex access,
+and composite operation without chipselect de-activation, is available using
+the SPI_IOC_MESSAGE(N) request.
+
+Several ioctl() requests let your driver read or override the device's current
+settings for data transfer parameters:
+
+    SPI_IOC_RD_MODE, SPI_IOC_WR_MODE ... pass a pointer to a byte which will
+	return (RD) or assign (WR) the SPI transfer mode.  Use the constants
+	SPI_MODE_0..SPI_MODE_3; or if you prefer you can combine SPI_CPOL
+	(clock polarity, idle high iff this is set) or SPI_CPHA (clock phase,
+	sample on trailing edge iff this is set) flags.
+
+    SPI_IOC_RD_LSB_FIRST, SPI_IOC_WR_LSB_FIRST ... pass a pointer to a byte
+	which will return (RD) or assign (WR) the bit justification used to
+	transfer SPI words.  Zero indicates MSB-first; other values indicate
+	the less common LSB-first encoding.  In both cases the specified value
+	is right-justified in each word, so that unused (TX) or undefined (RX)
+	bits are in the MSBs.
+
+    SPI_IOC_RD_BITS_PER_WORD, SPI_IOC_WR_BITS_PER_WORD ... pass a pointer to
+	a byte which will return (RD) or assign (WR) the number of bits in
+	each SPI transfer word.  The value zero signifies eight bits.
+
+    SPI_IOC_RD_MAX_SPEED_HZ, SPI_IOC_WR_MAX_SPEED_HZ ... pass a pointer to a
+	u32 which will return (RD) or assign (WR) the maximum SPI transfer
+	speed, in Hz.  The controller can't necessarily assign that specific
+	clock speed.
+
+NOTES:
+
+    - At this time there is no async I/O support; everything is purely
+      synchronous.
+
+    - There's currently no way to report the actual bit rate used to
+      shift data to/from a given device.
+
+    - From userspace, you can't currently change the chip select polarity;
+      that could corrupt transfers to other devices sharing the SPI bus.
+      Each SPI device is deselected when it's not in active use, allowing
+      other drivers to talk to other devices.
+
+    - There's a limit on the number of bytes each I/O request can transfer
+      to the SPI device.  It defaults to one page, but that can be changed
+      using a module parameter.
+
+    - Because SPI has no low-level transfer acknowledgement, you usually
+      won't see any I/O errors when talking to a non-existent device.
+
+
+FULL DUPLEX CHARACTER DEVICE API
+================================
+
+See the sample program below for one example showing the use of the full
+duplex programming interface.  (Although it doesn't perform a full duplex
+transfer.)  The model is the same as that used in the kernel spi_sync()
+request; the individual transfers offer the same capabilities as are
+available to kernel drivers (except that it's not asynchronous).
+
+The example shows one half-duplex RPC-style request and response message.
+These requests commonly require that the chip not be deselected between
+the request and response.  Several such requests could be chained into
+a single kernel request, even allowing the chip to be deselected after
+each response.  (Other protocol options include changing the word size
+and bitrate for each transfer segment.)
+
+To make a full duplex request, provide both rx_buf and tx_buf for the
+same transfer.  It's even OK if those are the same buffer.

+Short users guide for SLUB
+--------------------------
+
+First of all slub should transparently replace SLAB. If you enable
+SLUB then everything should work the same (Note the word "should".
+There is likely not much value in that word at this point).
+
+The basic philosophy of SLUB is very different from SLAB. SLAB
+requires rebuilding the kernel to activate debug options for all
+SLABS. SLUB always includes full debugging but its off by default.
+SLUB can enable debugging only for selected slabs in order to avoid
+an impact on overall system performance which may make a bug more
+difficult to find.
+
+In order to switch debugging on one can add a option "slub_debug"
+to the kernel command line. That will enable full debugging for
+all slabs.
+
+Typically one would then use the "slabinfo" command to get statistical
+data and perform operation on the slabs. By default slabinfo only lists
+slabs that have data in them. See "slabinfo -h" for more options when
+running the command. slabinfo can be compiled with
+
+gcc -o slabinfo Documentation/vm/slabinfo.c
+
+Some of the modes of operation of slabinfo require that slub debugging
+be enabled on the command line. F.e. no tracking information will be
+available without debugging on and validation can only partially
+be performed if debugging was not switched on.
+
+Some more sophisticated uses of slub_debug:
+-------------------------------------------
+
+Parameters may be given to slub_debug. If none is specified then full
+debugging is enabled. Format:
+
+slub_debug=<Debug-Options>       Enable options for all slabs
+slub_debug=<Debug-Options>,<slab name>
+				Enable options only for select slabs
+
+Possible debug options are
+	F		Sanity checks on (enables SLAB_DEBUG_FREE. Sorry
+			SLAB legacy issues)
+	Z		Red zoning
+	P		Poisoning (object and padding)
+	U		User tracking (free and alloc)
+	T		Trace (please only use on single slabs)
+
+F.e. in order to boot just with sanity checks and red zoning one would specify:
+
+	slub_debug=FZ
+
+Trying to find an issue in the dentry cache? Try
+
+	slub_debug=,dentry_cache
+
+to only enable debugging on the dentry cache.
+
+Red zoning and tracking may realign the slab.  We can just apply sanity checks
+to the dentry cache with
+
+	slub_debug=F,dentry_cache
+
+In case you forgot to enable debugging on the kernel command line: It is
+possible to enable debugging manually when the kernel is up. Look at the
+contents of:
+
+/sys/slab/<slab name>/
+
+Look at the writable files. Writing 1 to them will enable the
+corresponding debug option. All options can be set on a slab that does
+not contain objects. If the slab already contains objects then sanity checks
+and tracing may only be enabled. The other options may cause the realignment
+of objects.
+
+Careful with tracing: It may spew out lots of information and never stop if
+used on the wrong slab.
+
+SLAB Merging
+------------
+
+If no debugging is specified then SLUB may merge similar slabs together
+in order to reduce overhead and increase cache hotness of objects.
+slabinfo -a displays which slabs were merged together.
+
+Getting more performance
+------------------------
+
+To some degree SLUB's performance is limited by the need to take the
+list_lock once in a while to deal with partial slabs. That overhead is
+governed by the order of the allocation for each slab. The allocations
+can be influenced by kernel parameters:
+
+slub_min_objects=x		(default 8)
+slub_min_order=x		(default 0)
+slub_max_order=x		(default 4)
+
+slub_min_objects allows to specify how many objects must at least fit
+into one slab in order for the allocation order to be acceptable.
+In general slub will be able to perform this number of allocations
+on a slab without consulting centralized resources (list_lock) where
+contention may occur.
+
+slub_min_order specifies a minim order of slabs. A similar effect like
+slub_min_objects.
+
+slub_max_order specified the order at which slub_min_objects should no
+longer be checked. This is useful to avoid SLUB trying to generate
+super large order pages to fit slub_min_objects of a slab cache with
+large object sizes into one high order page.

+	  This requires code in the application that is loaded

+	  to install an interrupt handler for Supplemental
+	  Interrupt 0, that sets RETI to 0xff600000 and writes
+	  bit 11 of SICB_SYSCR when bit 5 of SICA_SYSCR is 0.
+	  This causes Core B to stall when Supplemental Interrupt

+	  COREB_SRAM_INIT is cleared.

+ *
+ *    FanSpeed is the speed of the fan in rps
+ *
+ *    KSCALE is the prescaler value (1, 2, 4, 8, or 16)
+ *
+ * When reading, we need to solve for FanSpeed. When writing, we need to
+ * solve for KTACH.

+/* The biggest issue we deal with in this driver is that register writes are
+ * synced to the RTC frequency of 1Hz.  So if you write to a register and
+ * attempt to write again before the first write has completed, the new write
+ * is simply discarded.  This can easily be troublesome if userspace disables
+ * one event (say periodic) and then right after enables an event (say alarm).
+ * Since all events are maintained in the same interrupt mask register, if
+ * we wrote to it to disable the first event and then wrote to it again to
+ * enable the second event, that second event would not be enabled as the
+ * write would be discarded and things quickly fall apart.
+ *
+ * To keep this delay from significantly degrading performance (we, in theory,
+ * would have to sleep for up to 1 second everytime we wanted to write a
+ * register), we only check the write pending status before we start to issue
+ * a new write.  We bank on the idea that it doesnt matter when the sync
+ * happens so long as we don't attempt another write before it does.  The only
+ * time userspace would take this penalty is when they try and do multiple
+ * operations right after another ... but in this case, they need to take the
+ * sync penalty, so we should be OK.
+ *
+ * Also note that the RTC_ISTAT register does not suffer this penalty; its
+ * writes to clear status registers complete immediately.

  *  Serial driver for TX3927/TX4927/TX4925/TX4938 internal SIO controller
- *
- *  Revision History:
- *	0.30	Initial revision. (Renamed from serial_txx927.c)
- *	0.31	Use save_flags instead of local_irq_save.
- *	0.32	Support SCLK.
- *	0.33	Switch TXX9_TTY_NAME by CONFIG_SERIAL_TXX9_STDSERIAL.
- *		Support TIOCSERGETLSR.
- *	0.34	Support slow baudrate.
- *	0.40	Merge codes from mainstream kernel (2.4.22).
- *	0.41	Fix console checking in rs_shutdown_port().
- *		Disable flow-control in serial_console_write().
- *	0.42	Fix minor compiler warning.
- *	1.00	Kernel 2.6.  Converted to new serial core (based on 8250.c).
- *	1.01	Set fifosize to make tx_empry called properly.
- *		Use standard uart_get_divisor.
- *	1.02	Cleanup. (import 8250.c changes)
- *	1.03	Fix low-latency mode. (import 8250.c changes)
- *	1.04	Remove usage of deprecated functions, cleanup.
- *	1.05	More strict check in verify_port.  Cleanup.
- *	1.06	Do not insert a char caused previous overrun.
- *		Fix some spin_locks.
- *		Do not call uart_add_one_port for absent ports.
- *	1.07	Use CONFIG_SERIAL_TXX9_NR_UARTS.  Cleanup.
- *	1.08	Use platform_device.
- *		Fix and cleanup suspend/resume/initialization codes.

+ * linux/drivers/video/hecubafb.c -- FB driver for Hecuba controller
+ *
+ * Copyright (C) 2006, Jaya Kumar
+ * This work was sponsored by CIS(M) Sdn Bhd
+ *
+ * This file is subject to the terms and conditions of the GNU General Public
+ * License. See the file COPYING in the main directory of this archive for
+ * more details.
+ *
+ * Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.
+ * This work was possible because of apollo display code from E-Ink's website
+ * http://support.eink.com/community
+ * All information used to write this code is from public material made
+ * available by E-Ink on its support site. Some commands such as 0xA4
+ * were found by looping through cmd=0x00 thru 0xFF and supplying random
+ * values. There are other commands that the display is capable of,
+ * beyond the 5 used here but they are more complex.
+ *
+ * This driver is written to be used with the Hecuba display controller
+ * board, and tested with the EInk 800x600 display in 1 bit mode.
+ * The interface between Hecuba and the host is TTL based GPIO. The
+ * GPIO requirements are 8 writable data lines and 6 lines for control.
+ * Only 4 of the controls are actually used here but 6 for future use.
+ * The driver requires the IO addresses for data and control GPIO at
+ * load time. It is also possible to use this display with a standard
+ * PC parallel port.
+ *
+ * General notes:
+ * - User must set hecubafb_enable=1 to enable it
+ * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR

- *
- * This is the "low-level" comms layer.
- *
- * It is responsible for sending/receiving messages
- * from other nodes in the cluster.
- *
- * Cluster nodes are referred to by their nodeids. nodeids are
- * simply 32 bit numbers to the locking module - if they need to
- * be expanded for the cluster infrastructure then that is it's
- * responsibility. It is this layer's
- * responsibility to resolve these into IP address or
- * whatever it needs for inter-node communication.
- *
- * The comms level is two kernel threads that deal mainly with
- * the receiving of messages from other nodes and passing them
- * up to the mid-level comms layer (which understands the
- * message format) for execution by the locking core, and
- * a send thread which does all the setting up of connections
- * to remote nodes and the sending of data. Threads are not allowed
- * to send their own data because it may cause them to wait in times
- * of high load. Also, this way, the sending thread can collect together
- * messages bound for one node and send them in one block.
- *
- * I don't see any problem with the recv thread executing the locking
- * code on behalf of remote processes as the locking code is
- * short, efficient and never (well, hardly ever) waits.

+ *****   INTRODUCTION ***********
+ *   On the Blackfin, the interrupt structure allows remmapping of the hardware
+ *   levels.
+ * - I'm going to assume that the H/W level is going to stay at the default
+ *   settings. If someone wants to go through and abstart this out, feel free
+ *   to mod the interrupt numbering scheme.
+ * - I'm abstracting the interrupts so that uClinux does not know anything
+ *   about the H/W levels. If you want to change the H/W AND keep the abstracted
+ *   levels that uClinux sees, you should be able to do most of it here.
+ * - I've left the "abstract" numbering sparce in case someone wants to pull the
+ *   interrupts apart (just the TX/RX for the various devices)
+ *******************************************************************************/

+ * Machine specific interrupt sources.
+ *
+ * Adding an interrupt service routine for a source with this bit
+ * set indicates a special machine specific interrupt source.
+ * The machine specific files define these sources.
+ *
+ * The IRQ_MACHSPEC bit is now gone - the only thing it did was to
+ * introduce unnecessary overhead.
+ *
+ * All interrupt handling is actually machine specific so it is better
+ * to use function pointers, as used by the Sparc port, and select the
+ * interrupt handling functions when initializing the kernel. This way
+ * we save some unnecessary overhead at run-time.

+/* Core file format: The core file is written in such a way that gdb
+   can understand it and provide useful information to the user (under
+   linux we use the 'trad-core' bfd).  There are quite a number of
+   obstacles to being able to view the contents of the floating point
+   registers, and until these are solved you will not be able to view the
+   contents of them.  Actually, you can read in the core file and look at
+   the contents of the user struct to find out what the floating point
+   registers contain.
+   The actual file contents are as follows:
+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
+   in the file.  Directly after this is a copy of the task_struct, which
+   is currently not used by gdb, but it may come in useful at some point.
+   All of the registers are stored as part of the upage.  The upage should
+   always be only one page.
+   DATA: The data area is stored.  We use current->end_text to
+   current->brk to pick up all of the user variables, plus any memory
+   that may have been malloced.  No attempt is made to determine if a page
+   is demand-zero or if a page is totally unused, we just cover the entire
+   range.  All of the addresses are rounded in such a way that an integral
+   number of pages is written.
+   STACK: We need the stack information in order to get a meaningful
+   backtrace.  We need to write the data from (esp) to
+   current->start_stack, so we round each of these off in order to be able
+   to write an integer number of pages.
+   The minimum core file size is 3 pages, or 12288 bytes.

+ * two bits in the software pte that are supposed to be set to zero in
+ * the TLB entry (24 and 25) for these indicators.  Although the level 1
+ * descriptor contains the guarded and writethrough/copyback bits, we can
+ * set these at the page level since they get copied from the Mx_TWC
+ * register when the TLB entry is loaded.  We will use bit 27 for guard, since
+ * that is where it exists in the MD_TWC, and bit 26 for writethrough.
+ * These will get masked from the level 2 descriptor at TLB load time, and
+ * copied to the MD_TWC before it gets loaded.

+ * Lock order:
+ *   1. slab_lock(page)
+ *   2. slab->list_lock
+ *
+ *   The slab_lock protects operations on the object of a particular
+ *   slab and its metadata in the page struct. If the slab lock
+ *   has been taken then no allocations nor frees can be performed
+ *   on the objects in the slab nor can the slab be added or removed
+ *   from the partial or full lists since this would mean modifying
+ *   the page_struct of the slab.
+ *
+ *   The list_lock protects the partial and full list on each node and
+ *   the partial slab counter. If taken then no new slabs may be added or
+ *   removed from the lists nor make the number of partial slabs be modified.
+ *   (Note that the total number of slabs is an atomic value that may be
+ *   modified without taking the list lock).
+ *
+ *   The list_lock is a centralized lock and thus we avoid taking it as
+ *   much as possible. As long as SLUB does not have to handle partial
+ *   slabs, operations can continue without any centralized lock. F.e.
+ *   allocating a long series of objects that fill up slabs does not require
+ *   the list lock.
+ *
+ *   The lock order is sometimes inverted when we are trying to get a slab
+ *   off a list. We take the list_lock and then look for a page on the list
+ *   to use. While we do that objects in the slabs may be freed. We can
+ *   only operate on the slab if we have also taken the slab_lock. So we use
+ *   a slab_trylock() on the slab. If trylock was successful then no frees
+ *   can occur anymore and we can use the slab for allocations etc. If the
+ *   slab_trylock() does not succeed then frees are in progress in the slab and
+ *   we must stay away from it for a while since we may cause a bouncing
+ *   cacheline if we try to acquire the lock. So go onto the next slab.
+ *   If all pages are busy then we may allocate a new slab instead of reusing
+ *   a partial slab. A new slab has noone operating on it and thus there is
+ *   no danger of cacheline contention.
+ *
+ *   Interrupts are disabled during allocation and deallocation in order to
+ *   make the slab allocator safe to use in the context of an irq. In addition
+ *   interrupts are disabled to ensure that the processor does not change
+ *   while handling per_cpu slabs, due to kernel preemption.
+ *
+ * SLUB assigns one slab for allocation to each processor.
+ * Allocations only occur from these slabs called cpu slabs.
+ *
+ * Slabs with free elements are kept on a partial list.
+ * There is no list for full slabs. If an object in a full slab is
+ * freed then the slab will show up again on the partial lists.
+ * Otherwise there is no need to track full slabs unless we have to
+ * track full slabs for debugging purposes.
+ *
+ * Slabs are freed when they become empty. Teardown and setup is
+ * minimal so we rely on the page allocators per cpu caches for
+ * fast frees and allocs.
+ *
+ * Overloading of page flags that are otherwise used for LRU management.
+ *
+ * PageActive 		The slab is used as a cpu cache. Allocations
+ * 			may be performed from the slab. The slab is not
+ * 			on any slab list and cannot be moved onto one.
+ *
+ * PageError		Slab requires special handling due to debug
+ * 			options set. This moves	slab handling out of
+ * 			the fast path.
