Hi Heinrich,
As a matter of fact and strictly speaking, there are bunch of missing features;
- Boot manager (section 3)
- boot manager policy
- support for some of Boot option variables
- boot recovery
- various protocols,
- from section 11 to section 20 and
- from section 24 to section 30
- Firmware Update (Spec section 23)
- UEFI Byte Code(EBC) machine (Spec section 22)
- Secure boot (Spec section 31)
- Support for some of HII packages (section 33)
- HII configuration protocols (section 34)
- security&crypto-related protocols (section 36)
- Variables
- support for authentication
I don't think that we should list all of them, but we should definitely describe the *criteria* for what features be implemented and what not.
Alex suggested to base the scope of our implementation on the minimum requirements of this document:
Yeah, I heard that but "minimum" is always a moving target and
Server Base Boot Requirements System Software on ARM Platforms - Version 1.1 https://developer.arm.com/docs/den0044/latest/server-base-boot-requirements-...
this document yet has a much larger amount of requirements list than current U-Boot supports.

# Personally, I'd like to add "integration of DM and UEFI objects" :)
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
Heinrich
Thanks, -Takahiro Akashi
