This is a small program that converts NAND Flash images from raw to
the format used by hw/nand.c. I don't know if it should be included in
qemu (it's handy for me to have it included). What it does:
 - takes on standard input flash rootfs partition images generated
from some OpenEmbedded-based build systems (i.e. Poky or OpenZaurus)
 - offsets the image to the rootfs partition's start,
 - inserts proper jffs2 markers in the Out-Of-Band areas in the flash
so that Linux doesn't protest. Also inserts empty block jffs2 markers
and ECC where necessary.

Cheers,
Andrew
