+/** @file
+  EFI SMM Access2 Protocol as defined in the PI 1.2 specification.
+
+  This protocol is used to control the visibility of the SMRAM on the platform.
+  It abstracts the location and characteristics of SMRAM.  The expectation is
+  that the north bridge or memory controller would publish this protocol.
+
+  The principal functionality found in the memory controller includes the following: 
+  - Exposing the SMRAM to all non-SMM agents, or the "open" state
+  - Shrouding the SMRAM to all but the SMM agents, or the "closed" state
+  - Preserving the system integrity, or "locking" the SMRAM, such that the settings cannot be 
+    perturbed by either boot service or runtime agents
