 /** @file
-  This file declares SMM SMRAM Access abstraction protocol
+  This file declares SMM SMRAM Access abstraction protocol which is used to control 
+  the visibility of the SMRAM on the platform. The expectation is
+  that the north bridge or memory controller would publish this protocol. 
+  For example, the Memory Controller Hub (MCH) has the hardware provision for this 
+  type of control. Because of the protected, distinguished class of memory for IA-32 
+  systems, the expectation is that this protocol would be supported only on IA-32 systems.
