From 5cb18b3d7bff2a83275ee98af2a14eb9e21c93ab Mon Sep 17 00:00:00 2001 From: Stefan Berger <stefanb@linux.vnet.ibm.com> Date: Tue, 26 May 2015 16:51:07 -0400 Subject: TPM2 ACPI table support Add a TPM2 ACPI table if a TPM 2 is used in the backend. Also add an SSDT for the TPM 2. Rename tpm_find() to tpm_get_version() and have this function return the version of the TPM found, TPMVersion_Unspec if no TPM is found. Use the version number to build version specific ACPI tables. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.
