In linux kernel since version 3.10 (release Date: 2013-06-30)  
If you have a Intel Medfield or Merrifield/Edison platform, then
enable this option by saying Y or m. Distros will typically not
enable this option: Medfield devices are not available to
developers and while Merrifield/Edison can run a mainline kernel with
limited functionality it will require a firmware file which
is not in the standard firmware tree
