2013-10-03UBI: fastmap: fix backward compatibility with image_seqRichard Genoud1-3/+19
Some old UBI implementations (e.g. U-Boot) have not implemented the image sequence feature. So, when erase blocks are written, the image sequence in the ec header is lost (set to zero). UBI scan_all() takes this case into account (commits 32bc4820287a1a03982979515949e8ea56eac641 and 2eadaad67b2b6bd132eda105128d2d466298b8e3) But fastmap scan functions (ubi_scan_fastmap() and scan_pool()) didn't. This patch fixes the issue.

2013-08-20UBI: Fix invalidate_fastmap()Richard Weinberger1-4/+1
Onging tests uncovered that invalidate_fastmap() is broken. It must not call ubi_wl_put_fm_peb() because all PEBs used by the old fastmap have already been put back. Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2013-05-29UBI: fastmap break out of used PEB searchBrian Pomerantz1-1/+3
While searching for PEB matches for each volume in the used PEB list, the search fails to stop when the PEB is found. This patch adds a break in the inner loop to stop the search when it is matched.
