punt redundant libcrc32

2011-06-25T06:10:49+00:00

The libcrc32.a is only used in one place: mkfs.ubifs. But this also uses libmtd.a, and the only file in libcrc32.a is also in libmtd.a. So libcrc32.a itself is completely redundant. Punt! Signed-off-by: Mike Frysinger Signed-off-by: Artem Bityutskiy

nanddump: document, warn about future default --omitoob

2011-06-23T14:57:55+00:00

To work as a proper inverse to nandwrite, nanddump must not dump OOB data by default. This patch prints a warning regarding the future change. We also suggest using the new flag, `--oob', for transitioning to the next release with new default behavior. Note that we are changing `-o' to mean `--oob' in the next release, similar to `nandwrite -o'. This is a break from previous behavior. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

nanddump: add --oob option

2011-06-23T14:57:55+00:00

Adds an explicit option for including OOB data in our data dump. Currently, this is the default behavior, but in the next release, the default will be to exclude OOB data. This is done to mirror the '-o' option in nandwrite. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

nanddump: warn about new default BB handling

2011-06-23T14:57:55+00:00

In an upcoming release, we will no longer default to --bb=padbad. Instead, the default will be --bb=skipbad. This makes nanddump a better inverse operation to nandwrite. This patch prints warnings for users so that they get a chance to update their scripts before the default changes officially. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

nanddump: update help message for BB method changes

2011-06-23T14:57:55+00:00

--noskipbad will soon be replaced by --bb=dumpbad, and --omitbad is being removed entirely in favor of --bb=skipbad. This patch adds warnings when using inappropriate configurations and adds info to the help message. Please plan to migrate to the new usages shortly.

nanddump: remove --skipbad, leaving --bb=skipbad

2011-06-23T14:57:55+00:00

We are moving to unify bad block handling methods under the --bb=METHOD option. Since --skipbad has not been included in a mtd-utils release yet, we can safely replace it without a deprecation and phase-out period. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

nanddump: add --bb=METHOD option

2011-06-23T14:57:55+00:00

We have too many separate bad block handling methods: --omitbad --noskipbad --skipbad On top of these, we have the default option: that bad blocks are replaced with 0xFF. These options will be unified under --bb=METHOD. The end goal will be something like: ---------------------------------------------------------------------------------------------- Old option New option Comment ---------------------------------------------------------------------------------------------- --bb=padbad dump flash data, substituting 0xFF for any bad blocks --noskipbad --bb=dumpbad dump flash data, including any bad blocks --skipbad --bb=skipbad dump good data, completely skipping any bad blocks (new default) --omitbad N/A very similar to `skipbad' (DEPRECTATED) The BB options are all mutually exclusive, so we check that we do not have more than one BB option explicitly enabled on the command line by tracking whether or not a BB method has been set by the user.

mtdinfo: add regioninfo/eraseblock map display

2011-06-09T06:32:53+00:00

This brings the mtdinfo utility in line with the functionality of the flash_info utility. It dumps the erase regioninfo (if the devices has it) as well as showing a handy eraseblock map (if the user has requested it). The eraseblock map also shows which blocks are locked and which ones are bad. Signed-off-by: Mike Frysinger Signed-off-by: Artem Bityutskiy
