   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.

  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:
  16           <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>

  50           That memory map is used for example by kexec to set up efi virtual
  51           mapping the 2nd kernel, but can also be used for debugging purposes.
