Please drop the -full.bin, it wastes space.
Change -rootfs.bin to append-rootfs | pad-extra 128k, similar to how it
is handled on the octeon target. That is enough to ensure that it
re-creates the overlay filesystem on first boot.
Change the sysupgrade.tar image to:

IMAGE/sysupgrade.tar/squashfs := append-rootfs | pad-extra 128k | sysupgrade-tar rootfs=$$$$@

You can drop losetup, it is not necessary.
