   2 #  Provides SMM variable service.
   3 #
   4 #  This module installs SMM variable protocol into SMM protocol database,
   5 #  which can be used by SMM driver, and installs SMM variable protocol
   6 #  into BS protocol database, which can be used to notify the SMM Runtime
   7 #  Dxe driver that the SMM variable service is ready.
   8 #  This module should be used with SMM Runtime DXE module together. The
   9 #  SMM Runtime DXE module would install variable arch protocol and variable
  10 #  write arch protocol based on SMM variable module.
  11 #
  12 #  Caution: This module requires additional review when modified.
  13 #  This driver will have external input - variable data and communicate buffer in SMM mode.
  14 #  This external input must be validated carefully to avoid security issues such as
  15 #  buffer overflow or integer overflow.
  16 #    The whole SMM authentication variable design relies on the integrity of flash part and SMM.
  17 #  which is assumed to be protected by platform.  All variable code and metadata in flash/SMM Memory
  18 #  may not be modified without authorization. If platform fails to protect these resources,
  19 #  the authentication service provided in this driver will be broken, and the behavior is undefined.
