OvmfPkg: add customized Tcg2ConfigPei clone 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.)

## @file
OvmfPkg: create Tcg12ConfigPei.inf Split Tcg2ConfigPei.inf into two variants: Tcg12ConfigPei.inf with TPM 1.2 support included and Tcg2ConfigPei.inf supporting TPM 2.0 only. This allows x86 builds to choose whenever TPM 1.2 support should be included or not by picking the one or the other inf file. Switch x86 builds to Tcg12ConfigPei.inf, so they continue to have TPM 1.2 support. No functional change.

This code movement requires moving the TPM_RSP_GET_TICKS / TestTpm12() helper structure / function too. While at it, give the TestTpm12() function @retval / @return documentation, plus wrap an overlong line in it. Functionally, this patch is a no-op.

Tpm12Support.h
OvmfPkg/Tcg2ConfigPei: skip TPM-1.2 detection when building for ARM/AARCH64 Dating back to commits f5cb3767038e and ddd34a818315d, the "ArmVirtPkg/ArmVirtQemu.dsc" platform includes the "OvmfPkg/Tcg/Tcg2Config/Tcg2ConfigPei.inf" module when the TPM2_ENABLE build flag is defined. This was regressed in commit 89236992913f, which added a Tpm12DeviceLib dependency to Tcg2ConfigPei. "ArmVirtQemu.dsc" does not resolve that class to any instance, so now we get a build failure: > build.py... > ArmVirtPkg/ArmVirtQemu.dsc(...): error 4000: Instance of library class > [Tpm12DeviceLib] is not found > in [OvmfPkg/Tcg/Tcg2Config/Tcg2ConfigPei.inf] [AARCH64] > consumed by module [OvmfPkg/Tcg/Tcg2Config/Tcg2ConfigPei.inf] The TPM-1.2 code in OvmfPkg/Tcg2ConfigPei is limited to a special use case (a kind of physical TPM-1.2 assignment), and that has never applied to "ArmVirtQemu.dsc". Short-circuit the TPM-1.2 detection in the ARM/AARCH64 builds of OvmfPkg/Tcg2ConfigPei, removing the Tpm12DeviceLib dependency. Functionally, this patch is a no-op on IA32 / X64.
