Richard Weinberger 74f2c6e9a4 ubi: Be more paranoid while seaching for the most recent Fastmap ... Since PEB erasure is asynchornous it can happen that there is more than one Fastmap on the MTD. This is fine because the attach logic will pick the Fastmap data structure with the highest sequence number. On a not so well configured MTD stack spurious ECC errors are common. Causes can be different, bad hardware, wrong operating modes, etc... If the most current Fastmap renders bad due to ECC errors UBI might pick an older Fastmap to attach from. While this can only happen on an anyway broken setup it will show completely different sympthoms and makes finding the root cause much more difficult. So, be debug friendly and fall back to scanning mode of we're facing an ECC error while scanning for Fastmap.
