Alex suggested to base the scope of our implementation on the minimum
requirements of this document:

Server Base Boot Requirements System Software on ARM Platforms - Version 1.1
https://developer.arm.com/docs/den0044/latest/server-base-boot-requirements-system-software-on-arm-platforms-version-11

The deficiencies that I listed in README.uefi are the user view.

I agree that we should also define our U-Boot internal development
targets and better DM-UEFI integration should be part of it.

Best regards
