[OpenWrt-Devel] [PATCH 5/6] layerscape: ls10121frdm: add sysupgrade

[Tomasz Maciej Nowak]

Instead of dangerous rewriting full chip with firmware.bin image to
update OpenWrt, add sysupgrade image. This image will be used to update
kernel and rootfs, leaving bootloader intact and making recovery
possible, without resorting to external hardware tools.
