The rpi has a pretty simple way of resetting the whole system. All it takes is to poke a few registers at a well defined location in MMIO space. This patch adds support for the EFI loader implementation to allow an OS to reset and power off the system when we're outside of boot time. Signed-off-by: Alexander Graf <agraf@suse.de>
