2012-11-27mmc: tegra: use bounce buffer APIsStephen Warren
Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In some cases (e.g. user load commands) this cannot be guaranteed by callers of the MMC APIs. To solve this, modify the Tegra MMC driver to use the new bounce_buffer_*() APIs. Note: Ideally, all U-Boot code will always provide address- and size- aligned buffers, so a bounce buffer will only ever be needed for user- supplied buffers (e.g. load commands). Ensuring this removes the need for performance-sucking bounce buffer cache management and memcpy()s. The one known exception at present is the SCR buffer in sd_change_freq(), which is only 8 bytes long. Solving this requires enhancing struct mmc_data to know the difference between buffer size and transferred data size, or forcing all callers of mmc_send_cmd() to have allocated buffers using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not enforced in any way at present, and so cannot be assumed by the core MMC code.

2012-11-27common: rework bouncebuf implementationStephen Warren
The current bouncebuf API requires all parameters to be passed to both bounce_buffer_start() and bounce_buffer_stop(). Modify the bouncebuf start function to accept a state structure as a parameter, and only require that state struct to be passed to the stop function. This simplifies usage of the bounce buffer by clients. Don't modify the data pointer, but rather store the temporary buffer in this state struct. The bouncebuf code ensures that client code can always use a single buffer pointer in the state structure, irrespective of whether a bounce buffer actually had to be allocated. Move cache management logic into the bounce buffer code, so that each client doesn't have to duplicate this. I believe there's no need to invalidate the buffer before a DMA operation, since flushing the cache should prevent any write-backs. Update the MXS MMC driver for this change.

2012-11-27bouncebuf: remove dummy implementationStephen Warren
If any driver ever needs to use the bounce buffer API, it always needs to use it. As such, providing a dummy implementation of those APIs when CONFIG_BOUNCE_BUFFER isn't defined does not make sense.

2012-11-26driver/mtd:IFC NAND:Initialise internal SRAM before any writePrabhakar Kushwaha
IFC-1.1.0 uses 28nm techenology for SRAM. This tech has known limitaion for SRAM i.e. "byte select" is not supported. Hence Read Modify Write is implemented in IFC for any "system side write" into sram buffer. Reading an uninitialized memory results in ECC Error from sram wrapper. Hence we must initialize/prefill SRAM buffer by any data before writing anything in SRAM from system side. To initialize SRAM user can use "READID" NAND command with read bytes equal to SRAM size.

2012-11-26powerpc/mpc85xx/p2020rdb-pca: Use L2 SRAM for SPL bootScott Wood
This allows DDR configuration to be deferred to the final U-Boot image, which is able to make use of SPD data. The SPL itself cannot use SPD due to code size constraints. It previously used fixed register values for DDR configuration, and those values did not work on the p2020rdb-pca board I tested with. It's possible that different revisions of the board require different settings. Using SPD eliminates that problem.

Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL and CONFIG_SPL_BUILD, respectively. CONFIG_NAND_SPL can be removed once the last mpc85xx nand_spl target is gone. CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't seem right to overload it for meaning SPL as well as nand_spl does. Even if it's somewhat appropriate for the main u-boot, the SPL itself isn't (necessarily) ramboot, and we don't have separate configs for SPL and main u-boot. It was also inconsistent, as other platforms such as mpc83xx didn't use CONFIG_RAMBOOT in this way. Signed-off-by: Scott Wood <scottwood@freescale.com> Cc: Andy Fleming <afleming@freescale.com>

2012-11-26powerpc/mpc8xxx: move LAW code into arch/powerpc/cpu/mpc8xxxScott Wood

2012-11-26powerpc/mpc85xx: fix TLB alignmentScott Wood
In the RAMBOOT/SPL case we were creating a TLB entry starting at CONFIG_SYS_MONITOR_BASE, and just hoping that the base was properly aligned for the TLB entry size. This turned out to not be the case with NAND SPL because the main U-Boot starts at an offset into the image in order to skip the SPL itself. Fix the TLB entry to always start at a proper alignment. We still assume that CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary thus requiring multiple TLB entries.
