acpi: Extend TPM2 ACPI table with missing log fields
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
