At this stage the YAFFS2 code base will support 512+16, but not in YAFFS2
mode. It will use 512+16 (yaffs1) backward compatability).

The reason for this is that the YAFFS2 format needs more tag bytes and
therefore a bigger oob area.

If/when oob-less yaffs comes into being, YAFFS2 format will be able to work
with 512+16.
