If you're using raw NAND chips you'll need a tiny board-specific glue
driver like spia.c to let the generic nand code know how to access the
chips.
You can't use FTL on it because that's for NOR flash. You can't use NFTL
because that requires the DiskOnChip ECC hardware, and in many places both
suffer from patent problems.
You can use JFFS on it, but JFFS2 hasn't yet been made to deal with NAND
flash - I'm happy to give you pointers if you want to fix that.
I'd also like to see someone write a SmartMedia-compatible translation
layer driver - that ought to be fairly simple to do too.
