| * UBI: init_volumes: Ignore volumes with no LEBsRichard Weinberger2014-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UBI assumes that ubi_attach_info will only contain ubi_ainf_volume structures for volumes with at least one LEB. In scanning mode this is true because UBI can nicely create a ubi_ainf_volume on demand while creating the EBA table. For fastmap this is not true, the fastmap on-flash structure has a list of all volumes, the ubi_ainf_volume structures are created from this list. So it can happen that an empty volume ends up in init_volumes(). We can easely deal with that by looking into ->leb_count too.

| * UBI: fastmap: do not miss bit-flipsBrian Norris2014-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The return value from 'ubi_io_read_ec_hdr()' was stored in 'err', not in 'ret'. This fix makes sure Fastmap-enabled UBI does not miss bit-flip while reading EC headers, events and scrubs the affected PEBs. This issue was reported by Coverity Scan.

| * UBI: avoid program operation on NOR flash after erasure interruptedQi Wang 王起 (qiwang)2014-09-111-32/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nor_erase_prepare() will be called before erase a NOR flash, it will program '0' into a block to mark this block. But program data into a erasure interrupted block can cause program timtout(several minutes at most) error, could impact other operation on NOR flash. So UBIFS can read this block first to avoid unneeded program operation. This patch try to put read operation at head of write operation in nor_erase_prepare(), read out the data. If the data is already corrupt, then no need to program any data into this block, just go to erase this block.
