2010-10-11README: Add new NAND env featuresScott Wood
CONFIG_ENV_SIZE does not need block alignment. Document CONFIG_ENV_RANGE and CONFIG_ENV_OFFSET_OOB. Signed-off-by: Scott Wood <scottwood@freescale.com>
2010-10-11Followup fixes on the mtdparts spread patchsetScott Wood
Consolidate some code in mtd_get_len_incl_bad(), and fix a condition where a valid partition could be reported as truncated if it has a good block at the end of the device (unlikely, since the BBT is usually there). Fix mid-block declarations in net_part_size(). Signed-off-by: Scott Wood <scottwood@freescale.com> Reviewed-by: Ben Gardiner <bengardiner@nanometrics.ca>
2010-10-11mtdparts: new add.spread: add part skipping bad blocksBen Gardiner
This patch adds a new 'mtdparts add' variant: add.spread. This command variant adds a new partition to the mtdparts variable but also increases the partitions size by skipping bad blocks and aggregating any additional bad blocks found at the end of the partition.

2010-10-11mtdparts: add new sub-command "spread"Ben Gardiner
This patch introduces the 'spread' sub-command of the mtdparts command. This command will modify the existing mtdparts variable by increasing the size of the partitions such that 1) each partition's net size is at least as large as the size specified in the mtdparts variable and 2) each partition starts on a good block. The new subcommand is implemented by iterating over the mtd device partitions and collecting a bad blocks count in each -- including any trailing bad blocks -- and then modifying that partitions's part_info structure and checking if the modification affects the next partition. This patch is based on a port of the 'dynnamic partitions' feature by Harald Welte <laforge@gnumonks.org>; ported from commit e05835df019027391f58f9d8ce5e1257d6924798 of git://git.openmoko.org/u-boot.git. Whereas Harald's feature used a compile-time array to specify partitions, the feature introduced by this patch uses the mtdparts environment variable.

2010-10-11mtdparts: show net size in mtdparts listBen Gardiner
This patch adds an additional column to the output of list_partitions. The additional column will contain the net size and a '(!)' beside it if the net size is not equal to the partition size.

2010-10-11mtd: add an mtd method for get_len_incl_bad()Ben Gardiner
The logic to 'spread' mtd partitions needs to calculate the length in the mtd device, including bad blocks. This patch introduces a new function, mtd_get_len_incl_bad that can return both the length including bad blocks and whether that length was truncated on the device. This new function will be used by the mtdparts spread command later in this series. The definition of the function is #ifdef'd out in configurations that do not use the new 'mtdparts spread' command.

2010-10-11mtdparts: regroup calls to get_mtd_device_nmBen Gardiner
The get_mtd_device_nm function is called in a couple places and the string that is passed to it is not really used after the calls. This patch regroups the calls to this function into a new function, get_mtd_info.

2010-10-11nand: remove dead code and suspend/resumeScott Wood
Get rid of the several "#if 0" sections that were keeping around Linux code that isn't relevant to U-Boot. Besides cluttering the code, these sections make tracking upstream changes harder, rather than easier. It's easy to discard obviously irrelevant diff hunks that patch rejects, but it's not as easy to notice hunks that apply cleanly to the #if 0 section, but *are* relevant to U-Boot and require modification elsewhere. Also remove suspend/resume, as this is not applicable to U-Boot. Removal saves 232 bytes on powerpc.

2010-10-11nand commands: make only "dump" repeatable.Scott Wood

2010-10-11nand erase: .spread, .part, .chip subcommandsScott Wood
A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html, Michele De Candia posted a patch to not count bad blocks toward the requested size to be erased. This is desireable when you're passing in something like $filesize, but not when you're trying to erase a partition. Thus, a .spread subcommand (named for consistency with http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced to make explicit the user's desire to erase for a given amount of data, rather than to erase a specific region of the chip. While passing $filesize to "nand erase" is useful, accidentally passing something like $fliesize currently produces quite unpleasant results, as the variable evaluates to nothing and U-Boot assumes that you want to erase the entire rest of the chip/partition. To improve the safety of the erase command, require the user to make explicit their intentions by using a .part or .chip subcommand. This is an incompatible user interface change, but keeping compatibility would eliminate the safety gain, and IMHO it's worth it. While touching nand_erase_opts(), make it accept 64-bit offsets and sizes, fix the percentage display when erase length is rounded up, eliminate an inconsistent warning about rounding up the erase length which only happened when the length was less than one block (rounding up for $filesize is normal operation), and add a diagnostic if there's an attempt to erase beginning at a non-block boundary.

2010-10-11cmd_nand: some infrastructure fixes and refactoringScott Wood
- If the current device is overridden by a named partition, - update the caller's pointer/index, rather than copy over the nand_info struct, and - be sure to call board_nand_select_device even when the device is overridden by a named partition. - Support 64-bit offsets/sizes in a few more places. - Refactor arg_off_size for added readability and flexibility, and some added checks such as partition size. - Remove redundant check for bad subcommands -- if there's no match it'll print usage when it gets to the end anyway.

2010-10-11nand util: read/write: accept unaligned lengthScott Wood
The underlying code in nand_base.c already supports non-page-aligned reads and writes, but the block-skipping wrapper code did not. With block skipping, an unaligned start address is not useful since you really want to be starting at the beginning of a partition -- or at least that's where you want to start checking for blocks to skip, but we don't (yet) support that. So we still require the start address to be aligned. An unaligned length, though, is useful for passing $filesize to the read/write command, and handling it does not complicate block skipping.

2010-10-07fsl: add support for NXID v1 EEPROM formatTimur Tabi
Freescale application note AN3638 describes an update to the NXID format, which stores MAC addresses and related data on an on-board EEPROM. The new version adds support for up to 23 MAC addresses, instead of just 8. Since the initial implementation of NXID had a "0" in the 'version' field, this new version is called "v1". Boards that are shipped with EEPROMs in the NXID v1 format should define CONFIG_SYS_I2C_EEPROM_NXID_1 instead of CONFIG_SYS_I2C_EEPROM_NXID.

2010-10-07powerpc/85xx: fix rev.2 job queue LIODN error stormKim Phillips
pumping line-rate traffic though a p4080 rev.2, which is configured to encrypt packets prior to forwarding through an IPsec tunnel, gets this error: of_platform ffe302000.jq: DECO: desc idx 22: LIODN error. DECO was trying to share from itself or from another DECO but the two Non-SEQ LIODN values didn't match or the "shared from" DECO's Descriptor required that the SEQ LIODNs be the same and they aren't. Since high traffic rates cause DECOs to begin to start sharing shared descriptors amongst themselves, and DECOs inherit job queue LIODNs when accessing shared descriptors, and a recently discovered rev.2 h/w erratum requires all sharing job queues in a partition have same liodn assignment, reassign the first job queue's liodn assignment to the rest.

2010-10-07fsl: verify writes to the MAC address EEPROMTimur Tabi
Update the code which writes to the on-board EEPROM so that it can detect if the write failed because the EEPROM is write-protected. Most of the 8xxx-class Freescale reference boards use an AT24C02 EEPROM to store MAC addresses and similar information. With this patch, if the EEPROM is protected, the "mac save" command will display an error message indicating that the write has not succeeded.

2010-10-07p1022ds: add audclk hwconfig setting to enable codec reference clockTimur Tabi
The Freescale P1022DS can use either a 12.288MHz or a 11.2896MHz reference clock for the audio codec, but by default both are disabled. Add a 'audclk' hwconfig option that allows the user to choose which clock he wants. The 12.288MHz clock allows the codec to use sampling rates of 16, 24, 32, 48, 64, and 96KHz. The 11.2896 clock allows 14700, 22050, 29400, 44100, 58800, and 88200Hz. Also configure a pin muxing to select some SSI signals, which will disable I2C1.

2010-10-07mpc8569mds: fix consuming long time while relocating code.Haiying Wang
The original code maps boot flash as non-cacheable region. When calling relocate_code in flash to copy u-boot from flash to ddr, every loop copy command is read from flash. The flash read speed will be the bottleneck, which consuming long time to do this operation. To resovle this, map the boot flash as write-through cache via tlb. And set tlb to remap the flash after code executing in ddr, to confirm flash erase operation properly done.

2010-10-07mpc8569mds: fix CONFIG_ENV_SIZEHaiying Wang
CONFIG_ENV_SIZE of MPC8569MDS was wrongly set to CONFIG_ENV_SECT_SIZE which is 128KB, so it took longer time to do crc32 calculation for ENV than it should do.

2010-10-07x86: Implement fully relocatable imageGraeme Russ
u-boot.bin can be loaded at any 4-byte aligned memory location and directly 'jumped' to using the 'go' command using the load address as the start address. Doing so performs a 'warm boot' which skips memory initialisation and other low-level initialisations, relocates U-Boot to upper memory and starts U-Boot in RAM as per normal 'cold boot'
2010-10-07x86: Use loops instead of memcpy/memset in board_init_fGraeme Russ
Provides a small speed increase and prepares for fully relocatable image. Downside is the TEXT_BASE, bss, load address etc must ALL be aligned on a a 4-byte boundary which is not such a terrible restriction as everything is already 4-byte aligned anyway
2010-10-07x86: Rearrange linker scriptGraeme Russ
Tidy up the linker script and discard some sections to save space
2010-10-07x86: Rename linker script symbolsGraeme Russ

2010-10-07x86: Set cold/warm boot flagGraeme Russ
2010-10-07x86: Place global data below stack before entering CGraeme Russ
By reserving space for the Global Data immediately below the stack during assembly level initialisation, the C declaration of the static global data can be removed, along with the 'RAM Bootstrap' function. This results in cleaner code, and the ability to pass boot-up flags from assembler into C
2010-10-07x86: Dont clobber %eax after getting memory sizeGraeme Russ
By using another register, reduce code size by one instruction
2010-10-07x86: Don't clobber %ebxGraeme Russ
%ebx will hold low-level boot flags and must be preserved
2010-10-07x86: Remove usage of %ebp as a return pointerGraeme Russ
Using %ebp as a return pointer prevents creating 'load anywhere' images
2010-10-07x86: Move ECC initialisation outside RAM initialisationGraeme Russ
To allow for 'load anywhere' images, the %ebp return pointer 'hack' must be removed, so we cannot have two 'calls' to get_mem_size
2010-10-07x86: Remove progress indication in low-level initGraeme Russ
Progress indication is not relocation friendly so remove it in preperation for full relocatability support
2010-10-07x86: Fix %ss and %esp in register structure for interruptsGraeme Russ
2010-10-07x86: Change compiler optionsGraeme Russ
Change to: - reparam=3 - no-from-pointer - no-stack-protector - preferred-stack-boundary=2 - no-top-level-reorder These options make the code a little smaller and faster
2010-10-07x86: Coding Style CleanupGraeme Russ
Perform some basic code cleanups of the x86 files
2010-10-07x86: Move loading of GTD to C codeGraeme Russ
Linux has C macros and code to load the GTD after switching to Protected Mode. Using these greatly simplifies the assembler code
2010-10-07x86: use gc sections to reduce image sizeGraeme Russ
Follow the discussion of Charles Manning and Mike Frysinger. Using gc_sections helps reduce image size.
2010-10-07x86: zboot updateGraeme Russ
The header of recent Linux Kernels includes the size of the image, and therefore is not needed to be passed to zboot. Still process the third parameter (size of image) in the event that an older kernel is being loaded
2010-10-07x86: Use TEXT_BASE in linker scriptsGraeme Russ
Use TEXT_BASE rather than a hard-coded base address on x86 linker scripts. This will allow any board to define its base link address without having to modify the linker script
2010-10-07x86: Make CONFIG_RELOC_FIXUP_WORKS generic for all x86 boardsGraeme Russ
Relocation is not board-specific for the x86 architectrure, so CONFIG_RELOC_FIXUP_WORKS can be defined globally in the config.h
2010-10-07x86: Remove bi_env from do_bdinfoGraeme Russ
Commit 55e97429d1e6cf0976711e4e0f29ea924b7e5917 removed the definition from /arch/i386/include/asm/u-boot.h but not its usage in do_bdinfo()
