2014-03-25ubi-utils: Add ubiblock toolEzequiel Garcia
With the addition of block device access to UBI volumes, we now add a simple userspace tool to access the new ioctls. Usage of this tool is as simple as it gets: $ ubiblock --create /dev/ubi0_0 will create a new block device /dev/ubiblock0_0, and $ ubiblock --remove /dev/ubi0_0 will remove the device. Artem: slightly changed the header comment. Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2012-08-23ubiattach: fail if kernel ignores max_beb_per1024Richard Genoud
If the kernel doesn't know the max_beb_per1024 parameter in the attach ioctl, but the call still succeeded ubi_attach and ubi_attach_mtd will return 1 instead of 0. In this case, the ubiattach command will detach the device and fail with an error message.

2012-08-23ubiattach: introduce max_beb_per1024 in UBI_IOCATTRichard Genoud
The ioctl UBI_IOCATT has been extended with max_beb_per1024 parameter. This parameter is used for adjusting the "maximum expected number of bad blocks per 1024 blocks" for each mtd device. The number of physical erase blocks (PEB) that UBI will reserve for bad block handling is now: whole_flash_chipset__PEB_number * max_beb_per1024 / 1024 This means that for a 4096 PEB NAND device with 3 MTD partitions: mtd0: 512 PEB mtd1: 1536 PEB mtd2: 2048 PEB the commands: ubiattach -m 0 -d 0 -b 20 /dev/ubi_ctrl ubiattach -m 1 -d 1 -b 20 /dev/ubi_ctrl ubiattach -m 2 -d 2 -b 20 /dev/ubi_ctrl will attach mtdx to UBIx and reserve: 80 PEB for bad block handling on UBI0 80 PEB for bad block handling on UBI1 80 PEB for bad block handling on UBI2 => for the whole device, 240 PEB will be reserved for bad block handling. This may seems a waste of space, but as far as the bad blocks can appear every where on a flash device, in the worst case scenario they can all appear in one MTD partition. So the maximum number of expected erase blocks given by the NAND manufacturer should be reserve on each MTD partition.

2012-08-23libubi: kill ubi_attach_mtdArtem Bityutskiy
The 'ubi_attach_mtd()' is not used and it is redundant now. 'ubi_attach()' function may be used instead. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

2012-08-22UBI: sync ubi-user.h with kernel v3.6-rc1Richard Genoud
Also remove the eraseblock type support, because kernel commit a65a0eb6d198e058687a9214683bd1c418f20d39 set the dtype parameter as obsolete. Also adjust to some renames: * 'UBI_PROP_DIRECT_WRITE' -> 'UBI_VOL_PROP_DIRECT_WRITE' * 'struct ubi_set_prop_req' -> 'struct ubi_set_vol_prop_req'. * 'UBI_IOCSETPROP' -> 'UBI_IOCSETVOLPROP' Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

2010-02-18libubi: 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.

2008-01-23ubi-utils: remove all old toolsArtem Bityutskiy
Remove all old tools because I cannot maintain them and the original authors do not seem to have time for this. Some of the tools do not work properly, some are just vague and undocumented and seem to be oriented to the environment of the IBM guys. Nevertheless, I'll return the tool as is in the next commit, becouse they are still useful. This commit also adds a ubinize utility to generate UBI images.
