1 # The U-Boot loader of the OpenMesh devices requires image sizes and
2 # checksums to be provided in the U-Boot environment.
3 # The OpenMesh devices come with 2 main partitions - while one is active
4 # sysupgrade will flash the other. The boot order is changed to boot the
5 # newly flashed partition. If the new partition can't be booted due to
6 # upgrade failures the previously used partition is loaded.
