2011-09-11libmtd: modify `mtd_write' to cover OOB writesBrian Norris
To support the MEMWRITE ioctl, we will need a different sort of libmtd interface for writing to flash. We will expand mtd_write to include more functionality; for now, we just change the function definition and description as we begin to add the actual functionality.

2011-09-11mtd-utils: update mtd-abi.hBrian Norris
Kernel ABI header added a new ioctl, killed an old one, and exposed OOB modes to user-space. Plus, it added a lot of documentation. We have some trivial name changes for some MTD mode constants as well. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com>
2011-09-11nandwrite: consolidate buffer usageBrian Norris
Instead of using two different output buffers for OOB data, let's just use the same one for all output. This adds an extra memcpy, but it simplifies some future work, so it's worth it.

2011-08-25nandtest: print number of bits corrected during testBen Gardiner
The nandtest program monitors the corrected ecc stat to determine if an ECC correction has taken place during the last write-read. If so, it prints "ECC corrected". The mtd subsytem will store the number of bits corrected in the corrected ecc stat so update the nandtest output to print also the number of bits corrected when performing the test.

2011-08-23nanddump: kill usages of MEMSETOOBSEL ioctlBrian Norris
The ioctl MEMSETOOBSEL hasn't existed for a long time. Using it as a backup to MTDFILEMODE is pointless, so just remove every time it is used. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com>

2011-08-23nandwrite: cleanup "oobinfochanged" leftoversBrian Norris
We don't really use oobinfochanged anymore, since all the calls to the MEMSETOOBSEL ioctls are gone. The remaining usage of it is superfluous now, as the only case where it is changed is under the "noecc" condition and the only case where it is tested is under the "!noecc" condition. We also no longer need the "restoreoob" label and can instead simply close everything done with the single remaining label, "closeall". Note that `close(-1)' is legal, although useless. Finally, we move `old_oobinfo' into the only block of code in which it's used now.

2011-08-23nandwrite: kill -j, -y, and -f optionsBrian Norris
The legacy -j (--jffs2) and -y (--yaffs) options haven't been operational for a long time, since MEMSETOOBSEL was killed. I don't think anybody will miss these options (correct me if I'm wrong). They can be replaced by proper usage of MTD_OOB_AUTO modes. The -f (--forcelegacy) option went hand in hand with -j and -y. Now that -j and -y are gone, there's no use for -f. Kill it.

2011-08-23nandwrite: remove `autoplace' featuresBrian Norris
The `autoplace' option was meant to force an MTD_OOB_AUTO layout while writing to flash. This option has not been properly supported for a very long time, as the necessary ioctl, MEMSETOOBSEL, has been removed. Apparently nobody uses this option. Kill it. Other code depends on the availability of the `old_oobinfo' data, so we move some code within a block that handles autoplacement if it's *already* enabled. This, however, is inconsistent and should be cleaned up shortly. Note: this option may be re-implemented in the near future with the addition of a new ioctl that allows on-the-fly chaning of MTD OOB modes.

2011-08-16mtdinfo: consolidate help as display_help()Brian Norris

Line up columns better so that everything is more readable. Remove "Example 1" since `mtdinfo' does not print information when not given any arguments.

2011-08-16mtdinfo: don't open NULL pointer when getting region_info with `-a'Brian Norris
This "fixes" a regression found in: commit 266061ebd5d72391f0a0e831b018e8fc7fea68a1 mtdinfo: add regioninfo/eraseblock map display On certain flash (NOR flash that have eraseblock region info), `mtdinfo -a' tries to open the MTD node file, for use with the ioctl MEMGETREGIONINFO; however, we didn't supply a device node path to `mtdinfo -a', so it's using NULL, resulting in errors like: mtdinfo: error!: couldn't open MTD dev: (null) error 14 (Bad address) For now, we can just skip dumping region_info with the `-a' flag. If we find a better way to do this (e.g., export via sysfs, find device nodes via automatic routines, etc.), then we can kill the workaround and this FIXME should be removed. The regression was first reported at: http://lists.infradead.org/pipermail/linux-mtd/2011-July/037232.html The result of recent changes is that we cannot get region_info for devices via the `--all' option. We add a note in the help message warning that mtdinfo may find more info when given a device patch, e.g., /dev/mtdX.

2011-06-27rewrite build system to avoid recursionMike Frysinger
The ubi-utils/src/ subdir is tossed as it just complicates things for no real gain. The dictionary.h header is relocated to the ubi-utils/include/ since other headers in there need it. The top level clean is replaced with a `find -delete` on objects, so it might prune more than necessary, but many projects now do this sort of thing and no one complained there. A "mkdep" helper generates the actual rule, and the variables are used with "foreach" to expand these automatically. The tests subdir is updated only to reflect the ubi-utils source move. Otherwise, it is left untouched as making that non-recursive isn't really worth the effort. While we're gutting things, also through in kbuild style output while building to make things more legible.
