You should be able to partition the MTD device by the commandline or a
redboot table.
I believe jffs2 requires at least 5 'sectors' on the chip, though I've
not used it. You would need to check the layout of your device has
enough for it.
That's about the extent of my knowledge at the moment... I hope it gives
you enough to google on...
