The Tcg2ConfigPei module informs the firmware globally about the TPM device type, by setting the PcdTpmInstanceGuid PCD to the appropriate GUID value. The original module under SecurityPkg can perform device detection, or read a cached value from a non-volatile UEFI variable. OvmfPkg's clone of the module only performs the TPM2 hardware detection. This is what the module does: - Check the QEMU hardware for TPM2 availability only - If found, set the dynamic PCD "PcdTpmInstanceGuid" to &gEfiTpmDeviceInstanceTpm20DtpmGuid. This is what informs the rest of the firmware about the TPM type. - Install the gEfiTpmDeviceSelectedGuid PPI. This action permits the PEI_CORE to dispatch the Tcg2Pei module, which consumes the above PCD. In effect, the gEfiTpmDeviceSelectedGuid PPI serializes the setting and the consumption of the "TPM type" PCD. - If no TPM2 was found, install gPeiTpmInitializationDonePpiGuid. (Normally this is performed by Tcg2Pei, but Tcg2Pei doesn't do it if no TPM2 is available. So in that case our Tcg2ConfigPei must do it.)
