| 9 | If you say Y here, you are able to get EFI (Extensible Firmware | |
| 10 | Interface) variable information via sysfs. You may read, | |
| 11 | write, create, and destroy EFI variables through this interface. | |
| 12 | ||
| 13 | Note that using this driver in concert with efibootmgr requires | |
| 14 | at least test release version 0.5.0-test3 or later, which is | |
| 15 | available from Matt Domsch's website located at: | |
| 16 | <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz> | |

| 26 | Say Y here to enable use efivars as a backend to pstore. This | |
| 27 | will allow writing console messages, crash dumps, or anything | |

| 35 | Saying Y here will disable the use of efivars as a storage | |
| 36 | backend for pstore by default. This setting can be overridden | |

| 47 | Export efi runtime memory maps to /sys/firmware/efi/runtime-map. | |
| 48 | That memory map is used for example by kexec to set up efi virtual | |
