* This file provides two ACPI global NVS macros: ACPI_GNVS_ADDR and

* ACPI_GNVS_SIZE. They are to be used in platform's global_nvs.asl file
|
|
* to declare the GNVS OperationRegion, as well as write_acpi_tables()
|
|
* for the GNVS address runtime fix up.
|
|
*
|
|
* If using CONFIG_ACPI_GNVS_EXTERNAL, we don't need to locate the GNVS in
|
|
* DSDT, since it is created by code, so ACPI_GNVS_ADDR is unused.
