## @file
# Provides SMM variable service.
#
# This module installs SMM variable protocol into SMM protocol database,
# which can be used by SMM driver, and installs SMM variable protocol
# into BS protocol database, which can be used to notify the SMM Runtime
# Dxe driver that the SMM variable service is ready.
# This module should be used with SMM Runtime DXE module together. The
# SMM Runtime DXE module would install variable arch protocol and variable
# write arch protocol based on SMM variable module.
#
# Caution: This module requires additional review when modified.
# This driver will have external input - variable data and communicate buffer in SMM mode.
# This external input must be validated carefully to avoid security issues such as
# buffer overflow or integer overflow.
# The whole SMM authentication variable design relies on the integrity of flash part and SMM.
# which is assumed to be protected by platform. All variable code and metadata in flash/SMM Memory
# may not be modified without authorization. If platform fails to protect these resources,
# the authentication service provided in this driver will be broken, and the behavior is undefined.
