-  Instance of SMM memory check library.

-

-  SMM memory check library library implementation. This library consumes SMM_ACCESS2_PROTOCOL

-  to get SMRAM information. In order to use this library instance, the platform should produce

-  all SMRAM range via SMM_ACCESS2_PROTOCOL, including the range for firmware (like SMM Core

-  and SMM driver) and/or specific dedicated hardware.
