They are only useful if you are working directly on one of their proprietary servers. If in doubt, say "N". if GOOGLE_FIRMWARE config GOOGLE_SMI tristate "SMI interface for Google platforms" depends on X86 && ACPI && DMI help Say Y here if you want to enable SMI callbacks for Google platforms. This provides an interface for writing to and clearing the event log. If EFI_VARS 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.
