* include/asm-offsets.h: automatically generate assembler constantsWolfgang Denk2010-10-26-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | A recurrent issue is that certain C level constructs like sizeof() or offsetof() cannot be used in assembler files, which is inconvenient when such constructs are used in the definition of macro names etc. To avoid duplication of such definitions (and thus another cause of problems), we adapt the Linux way to automatically generate the respective definitions from the respective C header files. In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36 kernel tree. We also copy the concept of the include/generated/ directory which can be used to hold other automatically generated files as well. We start with an architecture-independent lib/asm-offsets.c which generates include/generated/generic-asm-offsets.h (included by include/asm-offsets.h, which is what will be referred to in the actual source code). Later this may be extended by architecture-specific arch/*/lib/asm-offsets.c files that will generate a include/generated/asm-offsets.h.

* mtd: add an mtd method for get_len_incl_bad()Ben Gardiner2010-10-11-1/+3
| | | | | | | | | | | | | | | The logic to 'spread' mtd partitions needs to calculate the length in the mtd device, including bad blocks. This patch introduces a new function, mtd_get_len_incl_bad that can return both the length including bad blocks and whether that length was truncated on the device. This new function will be used by the mtdparts spread command later in this series. The definition of the function is #ifdef'd out in configurations that do not use the new 'mtdparts spread' command.

* nand: remove dead code and suspend/resumeScott Wood2010-10-11-4/+0
| | | | | | | | | | | | | | | Get rid of the several "#if 0" sections that were keeping around Linux code that isn't relevant to U-Boot. Besides cluttering the code, these sections make tracking upstream changes harder, rather than easier. It's easy to discard obviously irrelevant diff hunks that patch rejects, but it's not as easy to notice hunks that apply cleanly to the #if 0 section, but *are* relevant to U-Boot and require modification elsewhere. Also remove suspend/resume, as this is not applicable to U-Boot. Removal saves 232 bytes on powerpc.

| | | | | | | | | | | | | 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>

* MTD:NAND: ADD new ECC mode NAND_ECC_HW_OOB_FIRSTSandeep Paulraj2009-08-26-0/+1
| | | | | | | | | | | | | | | | | 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.

* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-256/+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.

* 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).

* 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.
