In linux kernel since version 2.6.12  
The Common Flash Interface specification was developed by Intel,
AMD and other flash manufactures that provides a universal method
for probing the capabilities of flash devices. If you wish to
support any device that is CFI-compliant, you need to enable this
option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
for more information on CFI.
