Well, moving over the SEV code over to PlatformInitLib makes sense.

That should allow the AmdSev use pei-less boot, simliar to IntelTdx,
and further down the road allow unify AmdSev + IntelTdx variants into
a single firmware binary supporting both SevSnp and Tdx.

I don't think that should be part of the "unaccepted memory" patch
series though.

take care,
