SPI in both of them is implemented using an SSP controller. My questions are: - Should I comment my changes in this list, or just in the linux-arm list? - SSP code for the PXA2XX is placed inside its own arch directories. Could it be useful to move it into the SPI directories?

Into what? It's basically a nonstandard SPI interface; so, into the standard interface. (Of course SSP can be used for stuff that's not SPI.

Which is > why I said "eventually". > So... Returning to the main question. I have code for using SSP and SPI in IXP4XX, and it is based in the PXA2XX. The main problem is that I do not want to add whole new files for what is clearly just a modification. However the original code is not accesible because it is in the mach-pxa2xx directories. Which decision should I take so that my changes have greater chances of been accepted? Moving the files of pxa2xx or creating new ones? Or this is just a bad decision and I should not use the code of pxa2xx at all?
