I think we can benefit from providing (U)EFI what it wants. I say let
your (U)EFI loader payload prepare the HOB using the LB table.

Right, either write a new efiboot that would replace elfboot,
or make an ELF wrapper for (U)EFI. I for one prefer the latter
solution just because that's how the other payloads work.

Nice to hear from you! Seems like you are making good progress! :)
