TPM 2.0 UEFI Preboot Interface Test
This manual test uses the TrEE UEFI protocol to test interaction with the TPM. The test fails if the system is PCAT and has a TPM 2.0. This test uses UEFI protocols to verify that a TPM is present to test the RNG command in pre-boot, to locate and verify that the TPM2 table tests the Platform Reset Attack Mitigation and UEFI interface, and checks that PCR values do not change when devices are enumerated. It also tests for the TPM extend performance in a preOS environment.
