2011-09-11nandwrite: kill `--raw' optionBrian Norris
The `--raw' option has lost all usefulness as it overlapped with several other OOB modes. I cannot even figure out what it was actually intended to do, but I'm sure its functionality fits somewhere in the MTD_OPS_{AUTO_OOB,PLACE_OOB,RAW} options, which are mostly implemented in libmtd's mtd_write(). I don't think users need a warning for this one, unless someone can tell me what it actually was supposed to have done in the first place.

2011-09-11mtdutils: move OOB auto-layout into libmtd's mtd_writeBrian Norris
With the addition of the the new ioctl(MEMWRITE), we can use the kernel's internal OOB autoplacement option. It's a cleaner interface and avoids too much duplication of coding effort. This patch moves any legacy code (using MEMGETOOBSEL) into a legacy function in libmtd.c. It's not exactly a "pre-2.6.30" feature, so I'm not moving it to libmtd_legacy.c. Now, autoplacement features are only activated if we call mtd_write with mode == MTD_OPS_AUTO_OOB. This should fix some discrepancies for nandwrite, where we weren't handling OOB consistently (i.e., we had different functionality when the kernel did/didn't support MEMWRITE). But that also means that we now default to using MTD_OPS_PLACE_OOB instead of AUTO layout. To re-enable autoplacement, we can re-implement the `--autoplace' option that had previously rotted. This patch also cleans up a need for an extra OOB buffer in nandwrite. This has been tested a little in nandsim as well as on SLC NAND flash.

2011-09-11nandwrite: merge `mtd_write_oob' and `mtd_write' callsBrian Norris
Now that `mtd_write' can write to both OOB and data regions, we need to perform our `mtd_write' call only once. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com>
2011-09-11libmtd: support MEMWRITE ioctlBrian Norris
`mtd_write()' now will first attempt to use MEMWRITE. Then, if that doesn't exist, it will attempt to fall back to old methods for writing OOB and/or page data. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com>
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.

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".

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: 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.
