The FIS does not, at present, support NAND flash parts. This is because
it only supports NOR flash. To make this work you would probably need
to create a bridging driver to one of the eCos NAND flash libraries and
a translation layer to make the NAND appear, to RedBoot, to be NOR.
If you don't need FIS you can still run a filesystem on the NAND by
building in fileio support. This is known to work in RedBoot and adds
a number of new commands. YAFFS is the recommended filesystem for NAND
parts (though beware - it's not under quite the same license as eCos).
