* ODROID XU4: Update U-Boot on eMMC boot partition Update the U-Boot on the eMMC boot partition if present. Only write the first megabyte as the eMMC boot partition might be smaller than the SPL image and only the first megabyte is occupied by FW/BL1/BL2/TZSW (see https://wiki.odroid.com/odroid-xu4/software/partition_table#tab__odroid-xu341).
