Take a look at the patch that Jan Rovins posted on Thursday for the MCPN765 
board. It deals with it in a different way - by acknowledging that what you 
effectively have is a 64-bit bus.

The alternative is to deal with the flash as two entirely separate 32-bit 
pairs, and just have two separate map drivers giving access to even and odd 
words respectively.

I'd like to see the cfi_jedec code removed completely and JEDEC probing put 
in a separate probe function, rather than more special cases added to it.
