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