10  * This file provides two ACPI global NVS macros: ACPI_GNVS_ADDR and
11  * ACPI_GNVS_SIZE. They are to be used in platform's global_nvs.asl file
12  * to declare the GNVS OperationRegion, as well as write_acpi_tables()
13  * for the GNVS address runtime fix up.
14  *
15  * If using CONFIG_ACPI_GNVS_EXTERNAL, we don't need to locate the GNVS in
16  * DSDT, since it is created by code, so ACPI_GNVS_ADDR is unused.
