* Fix computation in nand_util.c:get_len_incl_badDaniel Hobi2009-12-07-1/+1
| | | | | | | | | | | | | | | Depending on offset, flash size and the number of bad blocks, get_len_incl_bad may return a too small value which may lead to: 1) If there are no bad blocks, nand_{read,write}_skip_bad chooses the bad block aware read/write code. This may hurt performance, but does not have any adverse effects. 2) If there are bad blocks, the nand_{read,write}_skip_bad may choose the bad block unaware read/write code (if len_incl_bad == *length) which leads to corrupted data.

* Clean-up of s3c24x0 nand driverkevin.morfitt@fearnside-systems.co.uk2009-10-13-37/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch re-formats the arm920t s3c24x0 nand driver in preparation for changes to add support for the Embest SBC2440-II Board. The changes are as follows: - re-indent the code using Lindent - make sure register layouts are defined using a C struct - replace the upper-case typedef'ed C struct names with lower case non-typedef'ed ones - make sure registers are accessed using the proper accessor functions - run checkpatch.pl and fix any error reports It assumes the following patch has been applied first: - [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009 - patches 1/4, 2/4 and 3/4 of this series Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for the SBC2440-II Board. Also, temporarily modified sbc2410x, smdk2400, smdk2410 and trab configs to use the mtd nand driver (which isn't used by any board at the moment), ran MAKEALL for all ARM9 targets and no new warnings or errors were found.

* Conditionally perform common relocation fixupsPeter Tyser2009-10-03-0/+2
| | | | | | | | | | | Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code.

* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-2/+2
| | | | | | | | | | | | | | | | This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform.

* MTD:NAND: ADD new ECC mode NAND_ECC_HW_OOB_FIRSTSandeep Paulraj2009-08-26-0/+59
| | | | | | | | | | | | | | | | | This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to support 4-bit ECC on TI DaVinci devices with large page (up to 2K) NAND chips. This ECC mode is similar to NAND_ECC_HW, with the exception of read_page API that first reads the OOB area, reads the data in chunks, feeds the ECC from OOB area to the ECC hw engine and perform any correction on the data as per the ECC status reported by the engine.

The ndfc_calculate_ecc routine change the order of getting the ECC code. /* The NDFC uses Smart Media (SMC) bytes order */ ecc_code[0] = p[2]; ecc_code[1] = p[1]; ecc_code[2] = p[3]; But in the Correction algorithm when calculating the byte offset location, the s1 is used as the upper part of the address. Which again reverse the order making the final byte offset address location incorrect. byteoffs = (s1 << 0) & 0x80; . . byteoffs |= (s0 >> 4) & 0x08; The order is change to read it in straight and let the correction function to revert it to SMC order.

* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-5/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

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