Is this in CVS yet? If not, I hope it will be there soon.
From what I see, this is going to be just what we need.
YAFFS2 does not need to write_oobfree as a seperate function (it is always
written as a single page write). YAFFS2 only needs read_oobfree.
However, YAFFS1 could use the write_oobfree function at some future date if
YAFFS1 gets moved to this interface to remove the current reliance on hanging
the ugly ECC parameter stuff through the interface.
I am pretty busy right now, but will try get the YAFFS2 side sorted ASAP. If
the YAFFS2 stuff is CVSed before the mtd then I'll just point people to this
