I implemented the UEFI Specification version 2.10, specifically focusing on
the functionality described in Section 18.4, which details the EFI Debug
Support Table feature. This implementation ensures support for
hardware-assisted debugging and provides a standardized mechanism for
debuggers to discover and interact with system-level debug resources.

  efi: add EFI_SYSTEM_TABLE_POINTER for debug
  efi: add EFI_DEBUG_IMAGE_INFO_TABLE for debug
  efi: add EFI_DEBUG_IMAGE_INFO for debug

I think this should be configurable, I suspect there would be usecases
where it would be useful to be able to disable this functionality.
