* UBI: add image sequence number to EC headerAdrian Hunter2009-07-05
| | | | | | | | | | | 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>

* UBI: remove pre-sqnum images supportArtem Bityutskiy2008-07-24
| | | | | | | | | | | | | | | | | | | | 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.

* UBI: make ubi-header.h localArtem Bityutskiy2008-04-17
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>
