[Xen-devel] [PATCH] [HVM] [1/2] Add support for TCG ACPI table 'TCPA'

[Stefan Berger <stefanb@xxxxxxxxxx>]

This patch add support for a TCG ACPI table called 'TCPA' to the
existing ACPI tables. The size of the logging table is set to 10kb for
now - it should be 64kb.
The ACPI table is generated if the probing for the TIS interface
succeeds.
I cleaned up the ACPI signatures in acpi2_0.h to be more readable.

The specification for the layout of these ACPI tables can be found here:

Extensions to the Bochs BIOS that use these ACPI extensions will follow.
