* Convert ISO-8859 files to UTF-8Albert ARIBAUD2011-08-04-1/+1
| | | | | | | | There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
* NAND: add support for reading ONFI page tableFlorian Fainelli2011-04-01-0/+69
| | | | | | | | | | | | This patch adds support for reading an ONFI page parameter from a NAND device supporting it. If this is the case, struct nand_chip onfi_version member contains the supported ONFI version, 0 otherwise. This allows NAND drivers past nand_scan_ident to set the best timings for the NAND chip.

* 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.

* 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.

| | | | | | | | | This patch adds concatenation support to the U-Boot MTD infrastructure.

* 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.

| | | | | | | | | 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>
* 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.

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

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-419/+1439
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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>
