U-Boot provides standard variables for load addresses, and filesystem-agnostic load-commands. Furthermore thanks to distro-boot, the device and partition from which the system boots is known. The new boot-script makes use of all this information. Tested on the only board that uses this boot-script: Clearfog Pro Signed-off-by: Josua Mayer <josua.mayer97@gmail.com>
