* flash: Fix CFI buffer size bugJohn Schmoller2009-08-13-1/+1
| | | | | | | | | | | | Fix bug introduced by 9c048b523413ae5f3ff34e00cf57569c3368ab51. The cfi_flash.c driver cast the flash buffer size to a uchar in flash_write_cfibuffer(). On some flash parts, (tested on Numonyx part PC32F512M29EWH), the buffer size is 1KB. Remove the cast to uchar to enable buffer sizes to be larger.

* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-1663/+0
| | | | | | | | | | | | | Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

* | issue write command to base for JEDEC flashPo-Yu Chuang2009-07-13-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For JEDEC flash, we should issue word programming command relative to base address rather than sector base address. Original source makes SST Flash fails to program sectors which are not on the 0x10000 boundaries. e.g. SST39LF040 uses addr1=0x5555 and addr2=0x2AAA, however, each sector is 0x1000 bytes. Thus, if we issue command to "sector base (0x41000) + offset(0x5555)", it sends to 0x46555 and the chip fails to recognize that address. This patch is tested with SST39LF040.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove CONFIG_SYS_DAVINCI_BROKEN_ECC option. It's not just nasty; it's also unused by any current boards, and doesn't even match the main U-Boot distributions from TI (which use soft ECC, or 4-bit ECC on newer chips that support it). DaVinci GIT kernels since 2.6.24, and mainline Linux since 2.6.30, match non-BROKEN code paths for 1-bit HW ECC. The BROKEN code paths do seem to partially match what MontaVista/TI kernels (4.0/2.6.10, and 5.0/2.6.18) do ... but only for small pages. Large page support is really broken (and it's unclear just what software it was trying to match!), and the ECC layout was making three more bytes available for use by filesystem (or whatever) code. Since this option itself seems broken, remove it. Add a comment about the MV/TI compat issue, and the most straightforward way to address it (should someone really need to solve it).

* nand/mpc512x: Add MPC512x NAND support (NFC)Stefan Roese2009-06-12-0/+693
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds NAND Flash Controller driver for MPC5121 revision 2. All device features, except hardware ECC and power management, are supported. This NFC driver replaces the one orignally posted by John Rigby: "[PATCH] Freescale NFC NAND driver" It's a port of the Linux driver version posted by Piotr Ziecik a few weeks ago. Using this driver has the following advantages (from my point of view): - Compatibility with the Linux NAND driver (e.g. ECC usage) - Better code quality in general - Resulting U-Boot image is a bit smaller (approx. 3k) - Better to sync with newer Linux driver versions The only disadvantage I can see, is that HW-ECC is not supported right now. But this could be added later (e.g. port from Linux driver after it's supported there). Using HW-ECC on the MCP5121 NFC has a general problem because of the ECC usage in the spare area. This collides with JFFS2 for example.

* Redundant Environment: protect full sector sizeWolfgang Denk2009-06-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several boards used different ways to specify the size of the protected area when enabling flash write protection for the sectors holding the environment variables: some used CONFIG_ENV_SIZE and CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even a mix of both for the "normal" and the "redundant" areas. Normally, this makes no difference at all. However, things are different when you have to deal with boards that can come with different types of flash chips, which may have different sector sizes. Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the biggest sector size, which may include several sectors on boards using the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the case that only the first of these sectors get protected, while the following ones aren't. This is no real problem, but it can be confusing for the user - especially on boards that use CONFIG_ENV_SECT_SIZE to protect the "normal" areas, while using CONFIG_ENV_SIZE_REDUND for the "redundant" area. To avoid such inconsistencies, I changed all sucn boards that I found to consistently use CONFIG_ENV_SECT_SIZE for protection. This should not cause any functional changes to the code.

| * Noisily disable the legacy NAND subsystem.Scott Wood2009-04-03-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Legacy NAND is marked for feature removal after April 2009 (i.e. this upcoming release). There are still several boards that reference it (though many do so only for disk-on-chip support which has been silently disabled for a while now). These boards will now fail to build with #error, though the code is still there if the user removes #error. The plan is to remove the code outright in the next release, along with any board code that refers to it (such as board/esd/common/auto_update.c). Also, remove the legacy NAND API description from README.nand. Signed-off-by: Scott Wood <scottwood@freescale.com>
