JFFS2 has complete control of a DiskOnChip. It's only an ASIC to do
hardware ECC and a handful of NAND flash chips. But JFFS2 doesn't yet
support NAND flash properly, so at the moment plain NOR linear flash is

Not right now, maybe soon.

Hard to get hold of now - most people stopped making it in favour of CF.
Cisco still use it, but obviously that's fairly expensive, being Cisco.
It's easy enough to make a map driver for it if you actually _have_ one,
but most people don't, so nobody's bothered to write that driver yet.

Just looking in the drivers/mtd/maps directory will give you some boards to
