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