For now this only supports boards with SCSI/UFS storage where U-Boot is flashed to the boot partition, and only U-Boot itself is updated. In the future we may also support updating additional firmware components (tz, hyp, xbl) as well as having U-Boot installed to other partitions (e.g. as a first-stage bootloader).
