Is there any sane reason to keep the split between EFI and U-Boot long
size alive? The x86_64 U-Boot port is getting along reasonably well from
what I can tell and 32bit UEFI implementations on 64-bit hosts are dying
out.

So can't we just remove all of that cruft altogether instead and just
have x86_64 U-Boot with 64bit EFI stub and i386 U-Boot with 32bit EFI
stub as only combinations?

That would dramatically simplify the code.
