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). This patch adds such support to the FSL-UPM driver. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
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.

2008-11-19UBI: Add basic UBI support to U-Boot (Part 8/8)Kyungmin Park
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. Some source code parts have been uncommented by "#ifdef UBI_LINUX". This makes it easier to compare this version with the Linux version and simplifies future UBI ports/bug-fixes from the Linux version.

2008-10-29NAND: sync with 2.6.27Scott Wood
This brings the core NAND code up to date with the Linux kernel. Since there were several drivers in Linux as of the last update that are not in u-boot, I'm not bringing over new drivers that have been added since in the absence of an interested party. I did not update OneNAND since it was recently synced by Kyungmin Park, and I'm not sure exactly what the common ancestor is. Signed-off-by: Scott Wood <scottwood@freescale.com>

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. The following drivers must be examined carefully and maybe rewritten to some degree: cpu/ppc4xx/ndfc.c cpu/arm926ejs/davinci/nand.c board/delta/nand.c board/zylonite/nand.c Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

2008-06-10NAND FSL UPM: driver re-write using the hwcontrol callbackWolfgang Grandegger
This is a re-write of the NAND FSL UPM driver using the more universal hwcontrol callback (instead of the cmdfunc callback). Here is a brief list of furher modifications: - For the time being, the UPM setup writing the UPM array has been removed from the driver and must now be done by the board specific code. - The bus width definition in "struct fsl_upm_nand" is now in bits to comply with the corresponding Linux driver and 8, 16 and 32 bit accesses are supported. - chip->dev_read is only set if fun->dev_ready != NULL, which is required for boards not connecting the R/B pin. - A few issue have been fixed with MxMR bit manipulation like in the corresponding Linux driver. Note: I think the "io_addr" field of "struct fsl_upm" could be removed as well, because the address is already determined by "nand->IO_ADDR_[RW]", but I'm not 100% sure. This patch has been tested on a TQM8548 modules with the NAND chip Micron MT29F8G08FABWP. This patch is based on the following patches posted to this list a few minutes ago: PPC: add accessor macros to clear and set bits in one shot 83xx/85xx/86xx: add more MxMR local bus definitions Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Acked-by: Anton Vorontsov <avorontsov@ru.mvista.com>
