2010-09-02ubi-utils: reformat help text to fit in 80 columnsJon Povey
Reformat the help text of ubiattach and ubidetach to display nicely on 80 column terminals, also fix a couple of bits that did not make sense. Signed-off-by: Jon Povey <jon.povey@racelogic.co.uk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-09-02ubi-utils: provide default value for /dev/ubi_ctrlJon Povey
Modify ubiattach and ubidetach to default to /dev/ubi_ctrl if not supplied rather than requiring the user to type it in every time. Also bump version from 1.0 to 1.1 Signed-off-by: Jon Povey <jon.povey@racelogic.co.uk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-09-01rename crc32 to mtd_crc32Artem Bityutskiy
Because of namespace collisions mkfs.ubifs uses crc32() implementation from /lib/libz.so.1, which generates incompatible CRC and later on the kernel reports many CRC errors. Fix this by re-naming mtd-utils' crc32 function to mtd_crc32. Reported-by: Jon Povey <Jon.Povey@racelogic.co.uk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-26libmtd: support MEMERASE64Artem Bityutskiy
This patch is base on Kevin Cernekee's patch posted to the MTD mailing list. It adds MEMERASE64 support to the 'mtd_erase()' call. Now it first tries to use MEMERASE64, and if that is not supported, falls back to the old MEMERASE ioctl. This patch also introduces an 'offs64_ioctl' flag to the libmtd descriptor. However, we cannot initialize it in 'libmtd_open()', because we need an MTD device node, which we do not have in 'libmtd_open()'. Thus, we firs mark this flag as "uninitialized", and at the first invocation of 'mtd_erase()' we initialize it. This also means that we have to pass the limbtd descriptor to 'mtd_erase()', to save the flag value. This, in turn, requires tweaking 'mtd_erase()' users. This is not very nice, but good enough so far. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-17libs: remove ubiutils-specific stuff from common.hArtem Bityutskiy
Now include/common.h contains things that really everyone can use. And all the stuff specific to ubi-utils is in ubi-utils/include/ubiutils-common.h Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-13mtd-utils: move libmtd source files to lib/ subdirectoryKevin Cernekee
Source files for libmtd, crc32, and fec are scattered throughout the tree. Move them to a central location so they can be built into a common "libmtd.a" library used by all mtd-utils programs. This patch only renames/deletes files and does not change the content. Also modify the build system and source code so that libmtd.a can be built from a "common" location (lib/). Statically link all utilities at the top level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common crc32 implementation.

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.

2010-01-15ubiformat: 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.

2009-09-28ubiformat/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.

2009-06-02libmts: recognize pre-MTD-sysfs kernels betterArtem Bityutskiy
Not-so-old linux kernel like 2.6.29 do already have "/sys/class/mtd/mtdX" directories, while very old kernels do not. But in 2.6.29 these directories do not contain any information. Anyway, the logic in libmtd which checked whether the system supports sysfs was broken, because it assumed that old systems do not even have "/sys/class/mtd/" directory. Fix this problem by checking for "/sys/class/mtd/mtdX/name". If this is present - the system really has sysfs support. This patch also adds an extra print to libmtd.
