It is OK for the first block to be marked bad. YAFFS does not care.
YAFFS does not use the first block at all, at present.=20

The first block is not used for two reasons:
i) I thought it would be a good idea to reserve the first block for any=20
future purpose. So far none has been found.
ii) "Block 0" in YAFFS is equivalent to the NULL pointer in C - it means=20
"invalid block".=20
