[PATCH v2 0/3] tpm2: Make TPM2 logs accessible for non-UEFI firmware

[Stefan Berger]

From: Stefan Berger <stefanb@xxxxxxxxxxxxx>

This series of patches extends the existing 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.
