Yes, sure. The SmmCpuFeatures{Read,Write}SaveStateRegister() functions
in OvmfPkg/Library/SmmCpuFeaturesLib can be removed in favor of the AMD
version of SmmSmramSaveStateLib.
There are a few more places in OvmfPkg/Library/SmmCpuFeaturesLib which
access the state, for example the functions handling CPU hutplug. They
use QEMU_SMRAM_SAVE_STATE_MAP today, which should be identical to the
AMD version, so once we have the AMD version merged into the tree ovmf
can just use that instead of its own copy.
take care,
Gerd
