# 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.
