2009-12-15Blackfin: workaround anomaly 05000310Barry Song
While fetching instructions at the boundary of L1 instruction SRAM, a false External Memory Addressing Error might be triggered. We should ignore this and continue on our way to avoid random crashes. Because hardware errors are not exact in the Blackfin architecture, we need to catch a few more common cases when the code flow changes and the signal is finally delivered.

2009-12-15Blackfin: drop ptrace() write support for fixed code/bootromMike Frysinger
These regions are either read-only and won't work anyways (bootrom), or we don't want people screwing with them because they're shared between all processes (fixed code). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: MPU: support XIP in async flash memoryBarry Song
The NOMPU code already supported executing in the async banks, so this brings the MPU code in line. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: drop 4KB reserve at end of memoryBarry Song
The point of this small chunk was to avoid anomaly 05000310. This never really seemed to do what it was intended though -- no valid CPLBs exist over the reserved memory, and there is often memory before it anyways (due to the uClinux MTD and/or reserved DMA region). Plus, it doesn't address the L1 instruction case. So drop this chunk as it wastes memory and is affront to humanity.

2009-12-15Blackfin: support smaller uncached DMA chunks for memory constrained systemsBarry Song
When working with 8 meg systems, forcing a 1 meg DMA chunk heavily cuts into the available resources. So support smaller chunks to better cover needs for these systems. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: push BF5Xx configs down into mach-specific KconfigsMike Frysinger
While we're moving the BF54x code, have the BF54xM variants select the normal BF54x values so that the rest of the Kconfig tree doesn't need to check the BF54xM variant everytime it wants to check the BF54x. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: finish_atomic_sections: optimize the RTS stepMike Frysinger
No point in returning to userspace just to have it immediately perform the RTS step. We have to update the PC anyways, so do the RTS too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: kgdb: punt dead codeSonic Zhang
None of these vars/funcs were being used. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: reject NULL callback in set_dma_callback()Mike Frysinger
It makes no sense to call this function with a NULL callback. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15bfin-otp: add BF51x to the supported arch listMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: punt dead/unused flash mem_init settingsMike Frysinger
I don't think these defines were ever used. At any rate, we have common bit defines for all parts as well as a Kconfig option to declare the EBIU async timings, and no one has really complained about this so far. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: gptimers: use unsigned timer/group idsMike Frysinger
Since we always use these ids as unsigned values, and we have some assert code to make sure they don't exceed a limit, avoid signed issues. Reported-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: don't walk VMAs when oopsingRobin Getz
If we're double faulting, then we have to assume the VMAs are not safe as broken pointers here will prevent full trace output for the double fault. Shouldn't be a big problem though as rarely is a double fault caused by code in userspace. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: force BFD target when linking modulesMike Frysinger
This allows us to use any Blackfin toolchain to create kernel modules (such as the FDPIC bfin-linux-uclibc toolchain). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: comment the FDPIC PTRACE definesMike Frysinger
This matches similar documentation for the FRV FDPIC code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-12-15Blackfin: add an uncompressed vmImage targetMike Frysinger
This is useful for quick tests where networks are faster than compression, and/or the compression code is broken. Reported-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: announce current cpu rev when bootingRobin Getz
User reports rarely include full information, so include this important tidbit up front. It's also good to know at a glance in general. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: unify DMA masksMike Frysinger
Every Blackfin variant has the same DMA bit masks, so avoid duplicating them over and over in each mach header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: fix typo in isp1760 platform nameMichael Hennerich
The driver changed from "isp1760-hcd" to "isp1760", so update resources to match. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: H8606/ip0x: drop redundant SPI ctl_reg settingsMike Frysinger
No need to set MSTR in .ctl_reg as the Blackfin SPI bus driver does this already for all parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: BF54x: punt useless "masks" for count/address MMRsMike Frysinger
There's no point in having mask defines when the entire MMR value is a count or address. i.e. applying a mask of -1 is pointless. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: punt unused MXVR masksMike Frysinger
There are no MXVR device drivers, and if someday there is, we can put these in a dedicated header rather than polluting the global namespace. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: punt OTP MMRsMike Frysinger
People should not be accessing OTP MMRs directly. They should instead go through the Blackfin ROM helper functions. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: BF51x: dump non-existent SPI/NFC MMRsMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: scrub unused watchdog mmr masksMike Frysinger
The watchdog code doesn't need these, and the other parts had these punted, so keep the global namespace clean. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: scrub unused RTC masksMike Frysinger
The RTC driver code doesn't need these, and the other parts had these punted, so keep the global namespace clean. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: unify BF547/8/9 headersMike Frysinger
No point in duplicating entire lists when we can simply tail into other parts for most of the MMRs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: fix some BF547 header copy & paste typosMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: rename BF542 host dma definesMike Frysinger
All the other BF54x parts had these defines renamed to avoid collision, but it looks the BF542 was missed somehow. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: punt cache lock documentationMichael Hennerich
The cache lock code was unused and punted, so punt the documentation too. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: coreb: switched to unlocked_ioctlMike Frysinger
We don't need the BKL and now people will stop looking at this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: convert DMA mutex to an atomic and drop redundant codeMike Frysinger
The DMA channel status field was encoding redundant info wrt the DMA MMR config register, and it was doing an incomplete job of checking all DMA channels (some drivers write directly to the config register). So drop the tristate field in favor of a binary atomic field. This simplifies the code in general, removes the implicit need for sleeping, and forces the suspend code to handle all channels properly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: update bfin_rotary definesMichael Hennerich
The driver was moved during the merge process, so update the defines to match the new location. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: push down asm/ includes and out of bfin-global.hMike Frysinger
Avoid including unnecessary headers all the time as well as circular includes with core requirements. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: BF51x/BF52x: fill out bfin_clear_PPI_STATUS()Mike Frysinger
All the arches define a helper macro to make things easy for driver code. Reported-by: Frank Van Hooft <frank@frankvh.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: bf537-stamp: need io.h for writeb() funcsBarry Song
Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: bf538: add support for extended GPIO banksMichael Hennerich
The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as the other ports on the part and the same way as all other Blackfin parts. The MMRs are programmed slightly different and they cannot be used to generate interrupts or wakeup a sleeping system. Since these guys don't fit into the existing code, create a simple gpiolib driver for them.
