#  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.
