2009-12-05add lzop decompression supportPeter Korsgaard
Add lzop decompression support to the existing lzo bitstream handling (think gzip versus zlib), and support it for uImage decompression if CONFIG_LZO is enabled. Lzop doesn't compress as good as gzip (~10% worse), but decompression is very fast (~0.7s faster here on a slow ppc). The lzop decompression code is based on Albin Tonnerre's recent ARM Linux lzo support patch. Cc: albin.tonnerre@free-electrons.com Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2009-11-07ARM: Use Linux version for unaligned access codeRemy Bohmer
The asm-arm/unaligned.h includes linux/unaligned/access_ok.h This file is unsafe to be used on ARM, since it does an unaligned memory accesses which fails on ARM. Lookin at Linux the basic difference seems to be the header "include/asm-arm/unaligned.h". The Linux version of "unaligned.h" does *not* include "access_ok.h" at all. It includes "le_byteshift.h" and "be_byteshift.h" instead.

2009-09-15Define ffs/fls for all architecturesSimon Kagstrom
UBIFS requires fls(), which is not defined for arm (and some other architectures) and this patch adds it. The implementation is taken from Linux and is generic. ffs() is also defined for those that miss it. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>

2009-08-26MTD:NAND: ADD new ECC mode NAND_ECC_HW_OOB_FIRSTSandeep Paulraj
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.

This patch adds a new "page" parameter to all NAND read_page/read_page_raw APIs.

2009-07-16Remove legacy NAND and disk on chip code.Scott Wood
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.

2009-06-12mtd: Update MTD infrastructure to support 64bit device sizeStefan Roese
This patch brings the U-Boot MTD infrastructure in sync with the current Linux MTD version (2.6.30-rc3). Biggest change is the 64bit device size support and a resync of the mtdpart.c file which has seen multiple fixes meanwhile.

2009-06-12mtd: Add MTD concat support to concatenate multiple MTD NOR devicesStefan Roese
This patch adds concatenation support to the U-Boot MTD infrastructure. By enabling CONFIG_MTD_CONCAT this MTD CFI wrapper will concatenate all found NOR devices into one single MTD device. This can be used by e.g by UBI to access a partition that spans over multiple NOR chips. Signed-off-by: Stefan Roese <sr@denx.de>
2009-03-23Add wait flags to support board/chip specific delaysWolfgang Grandegger
The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The corresponding Linux FSL UPM driver uses similar delay points at the same locations. To manage these extra delays in a more general way, I introduced the "wait_flags" field allowing the board-specific driver to specify various types of extra delay.

2009-03-23Add support for TQM-specific chip select logic to FSL-UPMWolfgang Grandegger
For the NAND chips on the TQM8548 modules, a special chip-select logic is used. It uses dedicated address lines to be set via UPM machine address register (mar).

2009-03-23Add multi chip support to the FSL-UPM driverWolfgang Grandegger
This patch adds support for multi-chip NAND devices to the FSL-UPM driver. The "dev_ready" callback of the "struct fsl_upm_nand" is now called with the argument "chip_nr" to allow testing the proper chip select line. The NAND support of the MPC8360ERDK is updated as well. No other boards are currently using the FSL UPM driver. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
2009-03-20UBIFS: Implement read-only UBIFS support in U-BootStefan Roese
The U-Boot UBIFS implementation is largely a direct copy from the current Linux version (2.6.29-rc6). As already done in the UBI version we have an "abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock() ...). This makes it possible to use the original Linux code with very little changes. And by this we can better update to later Linux versions. I removed some of the Linux features that are not used in the U-Boot version (e.g. garbage-collection, write support).

2009-03-20Add LZO decompressor supportStefan Roese
This patch adds LZO decompression support to U-Boot. It is needed for the upcoming UBIFS support, since UBIFS uses LZO as default compressor/ decompressor. Since we only support read-only in UBIFS, only the decompressor is needed. All this is copied with minor changes from the current Linux kernel version (2.6.28-rc8). This patch only implements this LZO decompressor support for PPC. Other platforms using UBIFS will have to add the required "include/asm/unaligned.h" as well. It should be fairly easy to copy this from the Linux source tree as I have done it for PPC in this patch. Signed-off-by: Stefan Roese <sr@denx.de>
2009-01-23NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPSWolfgang Grandegger
This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and changes the default from 8 to 1 for the legacy and the new MTD NAND layer. This allows to remove all NAND_MAX_CHIPS definitions in the board config files because none of the boards use multi chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440 define #define NAND_MAX_CHIPS CONFIG_SYS_MAX_NAND_DEVICE but that's bogus and did not work anyhow.

This patch adds basic UBI (Unsorted Block Image) support to U-Boot. It's based on the Linux UBI version and basically has a "OS" translation wrapper that defines most Linux specific calls (spin_lock() etc.) into no-ops.

2008-08-12Update MTD to that of Linux 2.6.22.1William Juul
A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.
