I've been meaning to send this set out again anyways. This is the patch I am currently using (on top of v3.0). Conceptually it's quite similar to the first patches I sent out but some implementation details were slightly reworked to account for the generalization of the McSPI driver to other silicon. I would say that the patch is close to mergable save the fact that there is currently no clean way to set up GPIO CS pins from a board file. I'll send the horrible hack I currently use shortly. If anyone has any ideas on how this might be done cleanly please let me know. It's sad that the mere lack of a configuration interface is the reason this isn't upstream. Cheers, - Ben
