It would seem that Intel should be able to provide it... there's nothing
magical or proprietary about it, and it's only a couple dozen
instructions. I'm not quite sure who to ask, though.
Really, you need Intel's 64-bit version of PiSmmCpuDxeSmm. At least the
SmmInit.{asm,S} files, and ideally all their other SMM support code.
Are there any Intel folks on the list who can authorize that? It seems
silly for you to have to write it from scratch.
