Remove the 'dev_major' and 'dev_minor' fields from the volume information structure, because these fields should be provided by the device information structure. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-06-12mtd-utils: support 4096+64 page sizesEnric Balletbo i Serra
Add support for oobsize 64 and writesize 4096 in nanddump & nandwrite. Artem: some more info from further e-mail exchange: > Are there flashes with the 4096 page / 64 spare combination? Could you > refer to one? May be any URL? I thought 4096 comes with 128. Much to my regret I can't provide a URL because is not public. IGEP v2 board has a Onenand with two dice of 2048/64 spare combination but mtd views 4096/64. The minimal write page is 4K (2K from first dice and 2K from second dice).

2010-05-22nandwrite: fix the bug of writing a yaffs2 image to NANDStanley.Miao
The tool mkyaffs2image doesn't know the oob layout of a NAND flash, so it puts the yaffs2 tags at the offset 0 of oob area, as a result, the image generated by mkyaffs2image is different with the image dumped by nanddump. Now adding a parameter "-r" for nandwrite to differentiate these images. Write a image generated by mkyaffs2image: $> nandwrite -a -o /dev/mtd3 yaffs2.bin Write a image dumped by nanddump: $> nandwrite -a -r /dev/mtd3 image.bin Signed-off-by: Stanley.Miao <stanley.miao@windriver.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

This reverts commit 13b77ef356e876f42f489f6a08840e12847135c5. We do not support block devices. This patch was pushed by accident.
2010-04-08ubiattach/ubidetach: add support to attach/detach by pathMika Westerberg

2010-04-08libubi: add support to attach/detach by MTD device pathMika Westerberg
struct ubi_attach_request now has additional field 'dev' that can contain path to the MTD device node in the filesystem. Also there are two new functions that are able to handle path to the MTD device node: ubi_attach() - attach MTD device by number or by path ubi_detach() - detach MTD device by path ubi_attach() works like ubi_attach_mtd() when it is passed empty req->dev, otherwise it looks up correct MTD device number based on the given device node path.

2010-02-15build: add option to not force largefile supportPeter Korsgaard

2010-01-15ubiformat: be consistent with sequence numbersArtem Bityutskiy
This commit fixes a stupid an nasty bug. When we flash an UBI image, we do not change its sequence numbers. But when we format the rest of the PEBs (beyond the flashed image), we use a random (or specified via cmdline) sequence number. As a result, we have a broken flash format and UBI refuses it, because half of it has one sequence number, another half has a different one. What we have to do instead, we have to substitute image's sequence number with ours.

2009-12-09flash_unlock: enhancing for unlocking of specified number of blocksVimal Singh
This patch enhances the flash_unlock utility to be able to do unlocking for specified blocks range. This patch also fixes calculation of 'length' as in previous patch. Say there are 240 blocks present in the device. Then: offset starts from: 0x0 and full size of device: 0x1E00000 doing: 240 * 0x20000 gives -> 0x1E00000 But last block address should be 0x1DE0000 (which spans for 0x20000 bytes, adding up to size of 0x1E00000) Signed-off-by: Vimal Singh <vimalsingh@ti.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-12-08flash_lock: fix length being passedVimal Singh
This patch fixes the 'length' calculation.

Then: offset starts from: 0x0 and full size of device: 0x1E00000 doing: 240 * 0x20000 gives -> 0x1E00000 But last block address should be 0x1DE0000 (which spans for 0x20000 bytes, adding upto size of 0x1E00000) Signed-off-by: Vimal Singh <vimalsingh@ti.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-09-28ubiformat/ubinize: Don't randomize 0xFFFFFFFF sequence numberMichael Roth
args.image_seq is of type uint32_t and was initialized to -1 which becomes 0xFFFFFFFF in this case. Later the value -1 was used as a flag that args.image_seq should be replaced with a randomized value. With the option --image-seq (-Q) a user could provide any sequence number at will. But when the user provided sequence number was 0xFFFFFFFF this was understood effectivly as -1 and got overridden by a randomized sequence number. So this patch change the programm flow to respect the principle of least surprise and never use a randomized sequence number when the user provide one at own will.

2009-08-11nandwrite: unified reading from standard input and from file - part 3Jehan Bing
Nandwrite tries to use lseek() when failing to write on a page. lseek() will fail when used on the standard input so nandwrite fails. This code replaces lseek with a buffer. When the data is read, it is put in a buffer (filebuf). This buffer is reset at each block boundary. So a "seek" just means reading from the beginning of the buffer. writebuf and oobreadbuf are now just pointers to locations in filebuf.
