#  Provides ACPI methods for TPM 2.0 support
#
#  Spec Compliance Info:
#     "TCG ACPI Specification Version 1.2 Revision 8"
#     "Physical Presence Interface Specification Version 1.30 Revision 00.52"
#       along with
#     "Errata Version 0.4 for TCG PC Client Platform Physical Presence Interface Specification"
#     "Platform Reset Attack Mitigation Specification Version 1.00"
#    TPM2.0 ACPI device object
#     "TCG PC Client Platform Firmware Profile Specification for TPM Family 2.0 Level 00 Revision 1.03 v51"
#       along with
#     "Errata for PC Client Specific Platform Firmware Profile Specification Version 1.0 Revision 1.03"
#
#  This driver implements TPM 2.0 definition block in ACPI table and
#  populates registered SMI callback functions for Tcg2 physical presence
#  and MemoryClear to handle the requests for ACPI method. It needs to be
#  used together with Tcg2 MM drivers to exchange information on registered
#  SwSmiValue and allocated NVS region address.
#
#  Caution: This module requires additional review when modified.
#  This driver will have external input - variable and ACPINvs data in SMM mode.
#  This external input must be validated carefully to avoid security issue.
