Erase the partition given in $3 (default: rootfs) and flash the contents

of image given in $1 into the image $2.

if [ ! -r "$1" ]; then echo "Usage: $0 []" exit -1 fi

uboot_offset=0 config_offset=64 kernel_offset=256 initfs_offset=1280 rootfs_offset=2304 # chinook

This value should be selected for Diablo based firmwares

It also require patching qemu to get proper size of flash partitions

(by default qemu has Chinook split).
