Recent extensions of the TPM2 ACPI table added 3 more fields including 12 bytes of start method specific parameters and Log Area Minimum Length (u32) and Log Area Start Address (u64). So, we define a new structure acpi_tpm2_phy that holds these optional new fields. The new fields allow non-UEFI systems to access the TPM2's log. The specification that has the new fields is the following: TCG ACPI Specification Family "1.2" and "2.0" Version 1.2, Revision 8 https://trustedcomputinggroup.org/wp-content/uploads/TCG_ACPIGeneralSpecification_v1.20_r8.pdf Cc: linux-acpi@vger.kernel.org Cc: Len Brown <lenb@kernel.org> Signed-off-by: Stefan Berger <stefanb@linux.ibm.com> Acked-by: Rafael J.
