Hi Vitaly

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 
patch.

Thanx!

Charles
