Prepare ENV settings for sheevaplugs to be OpenWRT ready.
+----------+
| UBOOT | >> 896 Kb (7x128) = uboot
+----------+
| ENV | >> 128 Kb = uboot_env
+----------+
| IMAGES | >> 23 Mb @ 1 Mb = image -> UIMAGE+UINITRD+FDT
+----------+
| ROOT(FS) | >> 488 Mb @ 24 Mb = root -> rootfs (ubifs)
+----------+
With (CC) TRUNK OpenWRT build (QUICK HOWTO) :
<INTERRUPT>
Marvell>> nand erase.part root
Marvell>> ubi part root
Marvell>> ubi remove rootfs
Marvell>> ubi create rootfs
Marvell>> usb reset
Marvell>> fatload usb 0:1 0x800000
sheevaplug/openwrt/openwrt-kirkwood-sheevaplug-rootfs.ubifs
Marvell>> ubi write 0x800000 rootfs ${filesize}
Marvell>> reset
