B/c due to the MTD layer rework, there's no way now to use custom
oobinfo in yaffs.
Therefore, as yaffs1 presumes the SmartMedia OOB layout one can either
read/write raw OOB but that will most probably break the bad block
handling, or implement a small shim layer putting spare OOB area into
SmartMedia OOB layout or back. Any other way will result in
incompatibility with the older version of yaffs1.
