There is *no possible way* that I am going to completely implement
HII, so big nak on this comment!
In general, my plan was to implement the minimal parts of these
protocols to get to the point where we can run SCT before implementing
the rest, so we at least have a way to test implementation against
compliance tests written against the spec (instead of our own tests
written against our interpretation of the spec). In the particular
case of HII, it includes things like forms based UI rendering, so I
don't think we'll ever implement the entire thing. Or if someone did,
we'd probably want to make it something that can be disabled at
compile time to keep footprint down.
Anyways, until we get to the point of loading option ROMs from PCI
cards in u-boot I don't think we really need a setup menu or complete
HII implementation ;-)

I was talking to Peter Jones about this, and he suggested something
that makes *way* more sense.. just build u-boot with '-mabi=ms_abi' on
x86_64 (at least conditionally if EFI_LOADER is enabled). That would
take a bit of work to annotate the os layer in sandbox to use sysv
abi, but that is a lot smaller of an interface than EFI_LOADER (which
is only going to continue to grow).
Anyways, other than that, I'll double check the function order issues
you mentioned, I mostly assumed that Leif had it right (and I don't
remember encountering any issues with that so far with
Shell.efi/SCT.efi).
Some of your comments could be resolved by just squashing my
"implement" patches with Leif's "stub" patches, but I didn't want to
do that without Leif's permission.
