* mtd: Update MTD infrastructure to support 64bit device sizeStefan Roese2009-06-12-8/+21
| | | | | | | | | | | 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.

* mtd: Add MTD concat support to concatenate multiple MTD NOR devicesStefan Roese2009-06-12-4/+29
| | | | | | | | | 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>
* Add wait flags to support board/chip specific delaysWolfgang Grandegger2009-03-23-1/+5
| | | | | | | | | | | | | | 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.

* Add support for TQM-specific chip select logic to FSL-UPMWolfgang Grandegger2009-03-23-0/+1
| | | | | | | | | 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>
* Add multi chip support to the FSL-UPM driverWolfgang Grandegger2009-03-23-1/+3
| | | | | | | | | | | 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>
* UBIFS: Implement read-only UBIFS support in U-BootStefan Roese2009-03-20-0/+85
| | | | | | | | | | | | | | | 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).

* Add LZO decompressor supportStefan Roese2009-03-20-0/+181
| | | | | | | | | | | | | | | | | 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>
* NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPSWolfgang Grandegger2009-01-23-13/+9
| | | | | | | | | | | | | | | | 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.

* UBI: Add basic UBI support to U-Boot (Part 8/8)Kyungmin Park2008-11-19-521/+0
| | | | | | | | | | | | | 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.

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-419/+1484
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* NAND FSL UPM: driver re-write using the hwcontrol callbackWolfgang Grandegger2008-06-10-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
