There are probably quite a few people with the requirement of one firmware
supporting both 512 and 2k NAND board variants.
Would it help to modify yaffs2 to automatically handle the yaffs1 case? ie
something along the lines of:
sniff mtd
if mtd page size == 512 then yaffs1 handling
else yaffs2 handling
That should be pretty straight forward to do and would save having to do the
decision making elsewhere.
Thoughts?
