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