[edk2-devel] [PATCH v7 06/31] OvmfPkg/ResetVector: pre-validate the data pages used in SEC phase

  Hi,

Hmm, TDX will re-use those pages for something else.  So as long as TDX
is happy with OVMF_SECTION_TYPE_SEC_MEM everything should work fine and
just mentioning that in the comments will be ok.

If not we might need a SEV_SECTION_TYPE_SEC_MEM to indicate the entry is
valid for SEV only and Intel can add a separate
TDX_SECTION_TYPE_SOMETHING_ELSE entry for the same address range.

take care,
  Gerd
