I think it's possible to run yaffs-direct under Linux, but a) not from
scratch, so you'll need to do additional mods and b) i'm not sure it's
legal from a licensing POV.
The performance drop is only a problem for 512b page NAND flashes, so
if you've got a 2k page Samsung NAND flash, you shouldn't probably
bother.
The last thing I'd like to say is that you're free to customize the
yaffs support/nand chip driver for your own chip to get rid of the
shim layer translating smartmedia layout into generic, and that will
speedup things.
Hope that helps
