Component Type: kbuild config
Description: EFI Variable Support via sysfs
More info: If you say Y here, you are able to get EFI (Extensible Firmware Interface) variable information via sysfs. You may read, write, create, and destroy EFI variables through this interface. Note that this driver is only retained for compatibility with legacy users: new users should use the efivarfs filesystem instead.
