2008-09-09Fix printf errors under -DDEBUGAndrew Klossner
Fix printf format-string/arg mismatches under -DDEBUG. These warnings occur with DEBUG defined for a platform using cpu/mpc85xx. Users of other architectures can unearth similar problems by adding the line "CFLAGS += -DDEBUG=1" in config.mk right after "CFLAGS += $(call cc-option,-fno-stack-protector)".

2008-08-12NAND: Scan bad blocks lazily.Ilya Yanok
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.

2008-08-12fsl_elbc_nand: Hard-code the FBAR/FPAR split.Scott Wood
The hardware has separate registers for block and page-within-block, but the division between the two has no apparent relation to the actual erase block size of the NAND chip. Signed-off-by: Scott Wood <scottwood@freescale.com>
2008-08-12fsl_elbc_nand: workaround for hangs during nand writeAnton Vorontsov
Using current driver elbc sometimes hangs during nand write. Reading back last byte helps though (thanks to Scott Wood for the idea). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
2008-08-12Freescale eLBC FCM NAND driverScott Wood
This is a driver for the Flash Control Machine of the enhanched Local Bus Controller found on some Freescale chips (such as the mpc8313 and the mpc8379). Signed-off-by: Scott Wood <scottwood@freescale.com>
2008-08-12Don't panic if a controller driver does ecc its own way.Scott Wood
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>
2008-08-12NAND: Make NAND driver less verbose per defaultStefan Roese
This patch turns off printing of bad blocks per default upon bootup. This can always be shown via the "nand bad" command later. Signed-off-by: Stefan Roese <sr@denx.de>
2008-08-12NAND: Change nand_wait_ready() to not call nand_wait()Stefan Roese
This patch changes nand_wait_ready() to not just call nand_wait(), since this will send a new command to the NAND chip. We just want to wait for the chip to become ready here. Signed-off-by: Stefan Roese <sr@denx.de>

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>
2008-08-11OneNAND: Remove unused parameters to onenand_verify_pageSteve Sakoman
The block and page parameters of onenand_verify_page() are not used. This causes a compiler error when CONFIG_MTD_ONENAND_VERIFY_WRITE is enabled. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Dirk Behme <dirk.behme@gmail.com>

2008-08-08CFI: allow for dynamically determined flash sizes and addressesWolfgang Denk
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. (will be used for example by the TQM8xxL boards) Signed-off-by: Wolfgang Denk <wd@denx.de>
2008-08-06cfi-flash: Added support to flash_real_protect for Atmel flash devicesRafael Campos
Some of the flash memories produced by ATMEL start in read-only mode. We need to unprotect it. This patch allows the AT49BV6416 to work with cfi_flash memories. Tested in the at91rm9200ek board.

2008-07-17cfi_flash: fix flash on BE machines with CFG_WRITE_SWAPPED_DATASebastian Siewior
This got broken by commits 93c56f212c [cfi_flash: support of long cmd in U-boot.] That command needs to be in little endian format on BE machines with CFG_WRITE_SWAPPED_DATA. Without this patch, the command 0xf0 gets saved on stack as 0x00 00 00 f0 and 0x00 gets written into the cmdbuf in case portwidth = chipwidth = 8bit.

2008-07-15cfi_flash: make the command u32 onlySebastian Siewior
This got changed by commit 93c56f212c [cfi_flash: support of long cmd in U-boot.] Long is the wrong type because it will behave differently on 64bit machines in a way that is probably not expected. u32 should be enough.

2008-07-10MTD/NAND: Fix printf format warning in nand codeStefan Roese

2008-07-09NAND: Rename DEBUG to MTDDEBUG to avoid namespace pollution.Scott Wood
This is particularly problematic now that non-NAND-specific code is including <nand.h>, and thus all debugging code is being compiled regardless of whether it was requested, as reported by Scott McNutt <smcnutt@psyent.com>. Signed-off-by: Scott Wood <scottwood@freescale.com>
2008-07-08jedec_flash: Fix AM29DL800BB device IDStefan Roese

2008-06-19cfi-flash: Fix problem in flash_toggle(), busy was not detected reliablyStefan Roese
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>
