You can find the specification at
www.amd.com/us-en/assets/content_type/ DownloadableAssets/cfi_r20.pdf

Promoters of the specification are :Intel, AMD, Fujitsu and Sharp,
plus i bet others implement it.

The SST 39VF160 supports CFI.

None at the moment. You are the third person interested in doing this
implementation. I suggest that before you start you drop an email to
the list and see what help you can get.
