+## @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.
