Nothing in the UEFI Requirements appendix is valuable.
The table of required boot services is unnecessary because it is an exact duplicate of the UEFI boot services list in the UEFI spec (and it also happens to be slightly incorrect) (UEFI 2.6.1). It is providing no value to include in EBBR as all UEFI implementations are required to implement the full set.
The tables of required core protocols are already specified in the UEFI spec (UEFI 2.6.1)
The table of required media i/o protocols are already required if the device supports booting from a disk device (UEFI 2.6.2).
The table of console protocols is similarly already required if a console device is present.
It isn't clear that HII protocols need to be required. U-Boot does implement them, but it doesn't appear to be a critical requirement on whether or not an OSV can support the platform.
The tables of optional UEFI protocols isn't adding any value because it doesn't require anything of implementers, and it doesn't provide any commentary on when the protocols should be included. This is just additional text.
Remove the lot to simplify the spec.
