ar71xx/all0258n: sysupgrade support
U-Boot on the ALL0258N needs offset, size and md5 for kernel and rootfs to be stored in the U-Boot environment. If the checksums don't match during boot, a failsafe-system is booted instead. This patch adds a board-specific sysupgrade hack for the all0258n which calculates and updates the checksums for the U-Boot environment. Signed-off-by: Daniel Golle <dgolle@allnet.de> SVN-Revision: 28700
