* NAND: Scan bad blocks lazily.Ilya Yanok2008-08-12-3/+7
| | | | | | | | | | Rather than scanning on boot, scan upon the first attempt to check the badness of a block. This speeds up boot when not using NAND, and reduces the likelihood of needing to reflash via JTAG if NAND becomes nonfunctional.

| | | | | | | | | | | | Some hardware, such as the enhanced local bus controller used on some mpc83xx chips, does ecc transparently when reading and writing data, rather than providing a generic calculate/correct mechanism that can be exported to the nand subsystem. The subsystem should not BUG() when calculate, correct, or hwctl are missing, if the methods that call them have been overridden. Signed-off-by: Scott Wood <scottwood@freescale.com>

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-2299/+2753
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

|/ | | | | | | | | | | The CFI driver allowed only for static initializers in the CFG_FLASH_BANKS_LIST definition, i. e. it did not allow to map several flash banks contiguously if the bank sizes were not known in advance, which kind of violates U-Boot's design philosophy.

* cfi-flash: Fix problem in flash_toggle(), busy was not detected reliablyStefan Roese2008-06-19-8/+4
| | | | | | | | | | | | | This patch simplifies flash_toggle() (AMD commandset), which is used to detect if a FLASH device is still busy with erase/program operations. On 800MHz Canyonlands/Glacier boards (460EX/GT) the current implementation did not detect the busy state reliably, resulting in non erased sectors etc. This patch now simplifies this function by "just" comparing the complete data-word instead of ANDing it with the command-word (0x40) before the compatison. It is done the same way in the Linux implementation chip_ready() in cfi_cmdset_0002.c. Signed-off-by: Stefan Roese <sr@denx.de>

* | NAND FSL UPM: driver re-write using the hwcontrol callbackWolfgang Grandegger2008-06-10-82/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* cfi-flash: Add CFG_FLASH_AUTOPROTECT_LISTMatthias Fuchs2008-04-25-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a configurable flash auto protection list that can be used to make U-Boot protect flash regions in flash_init(). The idea has been discussed on the u-boot mailing list starting on Nov 18th, 2007. Even this patch brings a new feature it is used as a bugfix for 4xx platforms where flash_init() does not completely protect the monitor's flash range in all situations. U-Boot protects the flash range from CFG_MONITOR_BASE to (CFG_MONITOR_BASE + monitor_flash_len - 1) by default. This does not include the reset vector at 0xfffffffc. Example: #define CFG_FLASH_AUTOPROTECT_LIST {{0xfff80000, 0x80000}} This config option will auto protect the last 512k of flash that contains the bootloader on board like APC405 and PMC405.

* | MTD/CFI: flash_read64 is defined a weak function (for SPARC)Daniel Hellstrom2008-03-29-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPARC has implemented __raw_readq, it reads 64-bit from any 32-bit address. SPARC CPUs implement flash_read64 which calls __raw_readq. For current SPARC architectures (LEON2 and LEON3) each read from the FLASH must lead to a cache miss. This is because FLASH can not be set non-cacheable since program code resides there, and alternatively disabling cache is poor from performance view, or doing a cache flush between each read is even poorer. Forcing a cache miss on a SPARC is done by a special instruction "lda" - load alternative space, the alternative space number (ASI) is processor implementation spcific and can be found by including <asm/processor.h>.
