+ Caution: This module requires additional review when modified.
+ This driver will have external input - variable data. It may be input in SMM mode.
+ This external input must be validated carefully to avoid security issue like
+ buffer overflow, integer overflow.
+ Variable attribute should also be checked to avoid authentication bypass.
+ 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.
