2012-10-03UBI: Add fastmap on-flash data structuresRichard Weinberger
Add the on-flash data structures neeed by fastmap to ubi-media.h Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2012-05-20UBI: add in hex the value for UBI_INTERNAL_VOL_START to commentJoel Reardon
Explicitly provide the first internal volume ID value in the comment for UBI_INTERNAL_VOL_START. This allows developers who, when adding features related to volume ids and observe unexpected very large volume ids, to grep for the observed value in the source code and find out immediately that it is expected behaviour.

2012-05-20UBI: amend comments after all the renamingsArtem Bityutskiy
This patch amends commentaries in scan.[ch] to match the new logic. Reminder - we did the restructuring to prepare the code for adding the fastmap. This patch also renames a couple of functions - it was too difficult to separate out that change and I decided that it is not too bad to have it in the same patch with commentaries changes.

2011-04-14UBI: use __packed instead of __attribute__((packed))Artem Bityutskiy
There was an attempt to standartize various "__attribute__" and other macros in order to have potentially portable and more consistent code, see commit 82ddcb040570411fc2d421d96b3e69711c670328. Note, that commit refers Rober Love's blog post, but the URL is broken, the valid URL is: http://blog.rlove.org/2005/10/with-little-help-from-your-compiler.html Moreover, nowadays checkpatch.pl warns about using __attribute__((packed)): "WARNING: __packed is preferred over __attribute__((packed))" It is not a big deal for UBI to use __packed, so let's do it.

2009-07-05UBI: add image sequence number to EC headerAdrian Hunter
An image sequence number is added to the UBI erase-counter header to be able determine if the root file system contains a mixture of old and new images (because the flashing failed to complete). A change to nolo is also needed for this to take effect. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-07-24UBI: remove pre-sqnum images supportArtem Bityutskiy
Before UBI got into mainline, there was a slight flash format change - we did not have sequence number support, then added it. We have carried full support of those ancient images till this moment. Now the support is removed, well, not fully removed. Now UBI will support only _clean_ old images, which were cleanly detached last time (just before kernel upgrade). This is most likely the case. But we will not support unclean ancient images. Surprisingly, this allows us to remove a big chunk of legacy code. And the same should be true for downgrading: clean images should downgrade fine, but unclean ones will not. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-07-24UBI: amend commentariesArtem Bityutskiy
Hch asked not to use "unit" for sub-systems, let it be so. Also some other commentaries modifications. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-04-17UBI: make ubi-header.h localArtem Bityutskiy
The new trend in linux is not to store headers which define on-media format in the include/ directory, but instead, store them locally. This is because these headers "do not define any kernel<->userspace interface". Do so for UBI as well. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
