There is a "swaponflash" mtd driver. See
Trying to swap on top of JFFS2 is a bad fit. Swapping has several
characteristics that make the problem much easier that the general
filesystem-on-NAND problem. In particular:
a) The CPU page size is a multiple of the NAND page size.
b) There's no need for a persistent index across reboots
Such a driver accessing a dedicated NAND partition ought to work just fine.
