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
