+/** @file
+  Definition of the MEFW global NVS area protocol.  This protocol
+  publishes the address and format of a global ACPI NVS buffer used as a communications
+  buffer between SMM/DXE/PEI code and ASL code.
+  @todo The format is derived from the ACPI reference code, version 0.95.
+
+  Note:  Data structures defined in this protocol are not naturally aligned.
