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