* mtd: nand: use loff_t for offsetJean-Christophe PLAGNIOL-VILLARD2009-07-07-10/+10
| | | | | | | | nand_util currently uses size_t which is arch dependent and not always a unsigned long. Now use loff_t, as does the linux mtd layer. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* mtd: Update MTD infrastructure to support 64bit device sizeStefan Roese2009-06-12-4/+7
| | | | | | | | | | | This patch brings the U-Boot MTD infrastructure in sync with the current Linux MTD version (2.6.30-rc3). Biggest change is the 64bit device size support and a resync of the mtdpart.c file which has seen multiple fixes meanwhile.

* NAND: Enable nand lock, unlock featureNishanth Menon2009-01-23-36/+43
| | | | | | | | | | | | | | | | Enable nand lock, unlock and status of lock feature. Not every device and platform requires this, hence, it is under define for CONFIG_CMD_NAND_LOCK_UNLOCK Nand unlock and status operate on block boundary instead of page boundary.

* NAND: Properly create JFFS2 cleanmarkers.Scott Wood2008-10-29-19/+11
| | | | | | | | | | | As reported by Ilko Iliev <iliev@ronetix.at>, the "nand erase clean" command is currently broken, and among other things causes all blocks to be marked bad. This implements it properly using MTD_OOB_AUTO, along with some indentation fixes. Signed-off-by: Scott Wood <scottwood@freescale.com>

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-114/+245
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* MTD/NAND: Fix printf format warning in nand codeStefan Roese2008-07-10-3/+3
| | | | | | | | | 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: 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>
