The CFI driver can work only with CFI-compliant (and some partially
compliant) devices. SPI NOR flash memory can't be CFI-compliant
because it doesn't have a parallel interface that's attached directly
to the memory bus.

OpenOCD has some support for SPI memory but it requires
target-specific driver. If you can find some docs and implement that
for cc3200, that would be great. I seem to remember cc3200 is also
using some undocumented "flash file system" and that's another
complication, you have to prepare an image in suitable format before
flashing.

Shame on TI for not being open enough with those chips (that said, TI
behaves nicely in many other regards).
