* MTD/NAND: Fix printf format warning in nand codeStefan Roese2008-07-10-4/+4
| | | | | | | | | This patch fixes NAND related printf format warning. Those warnings are now visible since patch dc4b0b38d4aadf08826f6c31270f1eecd27964fd [Fix printf errors.] by Andrew Klossner has been applied. Thanks, this is really helpful. Signed-off-by: Stefan Roese <sr@denx.de>
* NAND: Rename DEBUG to MTDDEBUG to avoid namespace pollution.Scott Wood2008-07-09-37/+70
| | | | | | | | | 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>

* 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>
* nand: Correct NAND erase percentage outputDirk Behme2008-05-28-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | For NAND erase sizes smaller than one NAND erase block, erase percentage output becomes grater than 100% e.g. -- cut -- > nand info Device 0: NAND 64MiB 1,8V 8-bit, sector size 16 KiB > nand erase 0x100000 0x2000 NAND erase: device 0 offset 0x100000, size 0x2000 Erasing at 0x100000 -- 200% complete. OK > -- cut -- Correct this and give user a warning that more is erased than specified: -- cut -- > nand erase 0x100000 0x2000 NAND erase: device 0 offset 0x100000, size 0x2000 Warning: Erase size 0x00002000 smaller than one erase block 0x00004000 Erasing 0x00004000 instead Erasing at 0x100000 -- 100% complete. OK > -- cut -- Signed-off-by: Dirk Behme <dirk.behme@gmail.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-81/+81
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* PATCH - Fix oob data copied into supplied bufferTroy Kisky2008-04-21-9/+8
| | | | | | | | | | | | | This patch correctly sets the oobavail variable and fixes a bug where the oob data was not valid when there where multiple groups in oobfree. First segment fixes a typo Second segment fixes a bug where oob data may be copied incorrectly. Third segment adds an error message when exiting due to write protect. Forth segment fixes a bug where oobavail may be set incorrectly. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
* Remove conflicting NAND IDMike Frysinger2008-04-17-2/+0
| | | | | | | | | | | There are two NAND entries with ID 0xDC and this obviously causes problems. In the kernel, they punted the first entry, so we should do the same.
