[PATCH v6 0/2] tpm2: Make TPM2 logs accessible for non-UEFI firmware

[Stefan Berger]

From: Stefan Berger <stefanb at linux.ibm.com>

This series of patches adds an optional extensions for the TPM2 ACPI table
with additional fields found in the TPM2 TCG ACPI specification (reference
is in the patch) that allow access to the log's address and its size. We
then modify the code that so far only enables access to a TPM 1.2's log for
a TPM2 as well. This then enables access to the TPM2's log on non-UEFI
system that for example run SeaBIOS.
