UEFI
====
Example FIT image description file demonstrating the usage of the
bootm command to launch UEFI binaries.
Two boot configurations are available to enable booting GRUB2 on QEMU,
the former uses a FDT blob contained in the FIT image, while the later
relies on the FDT provided by the board emulator.
