One of the things that is needed to align the YAFFS codebase for YAFFS2 is to 
make a cleaner division between the YAFFS guts and device specific routines. 
There are already some uglinesses in yaffs_guts to support hw ecc etc., so 
this repartitioning should help to make the system integrator's job easier 
too.

Herewith a repartitioning proposal. I'd like people to give this a read 
(particularly anyone who has dabbled with the yaffs_mtd interface  or 
equivalent) and comment.

Thanx
