[edk2-devel] [PATCH v2 3/3] Ovmf: enable TPM 1.2 support
marcandre.lureau at redhat.com

Thu Feb 13 13:12:22 UTC 2020
From: Marc-André Lureau <marcandre.lureau at redhat.com>
Enable TcgPei & TcgDxe modules to initialize a TPM 1.2 device and
measure boot environment.
Tpm12RequestUseTpm() returns success on any TPM interface, including
FIFO & CRB which are TPM 2.0. Check the actual interface with
Tpm12GetPtpInterfaceType(), and only detect 1.2 if it's a TIS.
