This provides an interface for writing to and clearing the event log. If CONFIG_EFI is also enabled this driver provides an interface for reading and writing NVRAM variables. config GOOGLE_COREBOOT_TABLE tristate "Coreboot Table Access" depends on ACPI || OF help This option enables the coreboot_table module, which provides other firmware modules access to the coreboot table. The coreboot table pointer is accessed through the ACPI "GOOGCB00" object or the device tree node /firmware/coreboot.
