Goodness this time around:
 
   - HII protocol, finally allows us to run the UEFI Shell!
     (experimantal, disabled by default)
   - efi selftest now available on Cortex-M
   - NVMe support for distro boot
   - Lots of code cleanup

The Human Interface Infrastructure is a complicated framework that
allows UEFI applications to draw fancy menus and hook strings using

U-Boot implements enough of its features to be able to run the UEFI

beware that your system might break with HII enabled.
