* mtdparts: regroup calls to get_mtd_device_nmBen Gardiner2010-10-11-15/+30
| | | | | | | | | | | | 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.

* nand: remove dead code and suspend/resumeScott Wood2010-10-11-328/+1
| | | | | | | | | | | | | | | 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.

* nand commands: make only "dump" repeatable.Scott Wood2010-10-11-8/+13
| | | | | | | | | The dump command is made to increment its address on repeat, as md does. Other commands do not make sense to issue repeatedly, and can be irritating when it happens accidentally, so don't.

* nand erase: .spread, .part, .chip subcommandsScott Wood2010-10-11-22/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cmd_nand: some infrastructure fixes and refactoringScott Wood2010-10-11-107/+167
| | | | | | | | | | | | | | | | - 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.

* nand util: read/write: accept unaligned lengthScott Wood2010-10-11-37/+63
| | | | | | | | | | | | | | | | 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.

| * x86: Implement fully relocatable imageGraeme Russ2010-10-07-24/+35
| | | | | | | | | | | | | | | | 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'
| * x86: Use loops instead of memcpy/memset in board_init_fGraeme Russ2010-10-07-17/+33
| | | | | | | | | | | | | | 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
| * x86: Rearrange linker scriptGraeme Russ2010-10-07-23/+21

| * x86: Place global data below stack before entering CGraeme Russ2010-10-07-37/+37
| | | | | | | | | | | | | | 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
| * x86: Dont clobber %eax after getting memory sizeGraeme Russ2010-10-07-3/+2

| * x86: Don't clobber %ebxGraeme Russ2010-10-07-7/+12
| | | | | | | | %ebx will hold low-level boot flags and must be preserved
| * x86: Remove usage of %ebp as a return pointerGraeme Russ2010-10-07-13/+12
| | | | | | | | Using %ebp as a return pointer prevents creating 'load anywhere' images
| * x86: Move ECC initialisation outside RAM initialisationGraeme Russ2010-10-07-14/+14
| | | | | | | | | | To allow for 'load anywhere' images, the %ebp return pointer 'hack' must be removed, so we cannot have two 'calls' to get_mem_size

| * x86: Move loading of GTD to C codeGraeme Russ2010-10-07-96/+57
| | | | | | | | | | Linux has C macros and code to load the GTD after switching to Protected Mode. Using these greatly simplifies the assembler code
| * x86: use gc sections to reduce image sizeGraeme Russ2010-10-07-5/+8
| | | | | | | | | | Follow the discussion of Charles Manning and Mike Frysinger. Using gc_sections helps reduce image size.
| * x86: zboot updateGraeme Russ2010-10-07-5/+13
| | | | | | | | | | | | 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
| * x86: Use TEXT_BASE in linker scriptsGraeme Russ2010-10-07-4/+4
| | | | | | | | | | | | 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
| * x86: Make CONFIG_RELOC_FIXUP_WORKS generic for all x86 boardsGraeme Russ2010-10-07-2/+2

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

I'd prefer to have program header loading be the default, but this would break historical behavior, so I'll leave section header loading as the norm. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
