The changes to DxeTcgPhysicalPresenceLib.c are due to the device we are using
in QEMU for presenting the supported PPI commands and results to the OS via
ACPI as well as to store the PPI opcode to execute.
Fails to build for microvm.

+ TcgPhysicalPresenceLib|OvmfPkg/Library/TcgPhysicalPresenceLibNull/DxeTcgPhysicalPresenceLib.inf
I guess this line is needed just next to Tcg2PhysicalPresenceLibNull
line?

(same problem on OvmfXen.dsc)

take care,
