2009-06-08nandwrite: amend loop conditionJehan Bing
If the file contains only a few bytes in the last page and the --oob option is selected, the loop may exit early (readlen < meminfo.oobsize). Most of the time it will still work though because the code tries to read the whole OOB in one chunk.

2008-12-26nandwrite: correct data readingArtem Bityutskiy
The "read" syscall does not necessarily return all the requested data, in which case the caller has to try again and read more. Take this into account when reading input data. This patch is an improved vestion of the original patch sent by Hai Zaar. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Tested-by: Hai Zaar <haizaar@codefidence.com>

2007-08-03Remove $Id:$ tagsJosh Boyer
The $Id:$ tags are left over from the old CVS repository. Several files have since been changed, and they generally have little value in a git repo so they should be removed. Signed-off-by: Josh Boyer <jwboyer@gmail.com>
2007-03-15MTD-Utils: fix handling of ioctl return value in nand-utilsFrank Haverkamp
Older kernel do not implement the MTDFILEMODE ioctl. In this case nandwrite and nanddump should have used MEMGETOOBSEL in combination with MEMSETOOBSEL. Unfortunately the return value of the unsucessfull ioctl is not -ENOTTY, but -1 and errno contains ENOTTY. This change fixes this issue. I have not tested all cornercases. Would be good if someone could do more careful testing than I did, or maybe reviewing is sufficient in this case.

2006-05-30Update mtd-abi.h and use new NAND ECC functionalityThomas Gleixner
The NAND rework exposes more information to userspace and has a different mechanism to read raw FLASH contents without ECC. Update nanddump and nandwrite. Use the new ECC statistics ioctl to inform the user about corrected and uncorrectable bitflips. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
