# devtype e.g. mmc/scsi etc
# devnum The device number of the given type
# bootpart The partition containing the boot files
# distro_bootpart The partition containing the boot files
# (introduced in u-boot mainline 2016.01)
# prefix Prefix within the boot partiion to the boot files
# kernel_addr_r Address to load the kernel to
# fdt_addr_r Address to load the FDT to
# ramdisk_addr_r Address to load the initrd to.
