Hi,

note that a previous version of the patch breaks spi on pxa machines:
tested on pxa250 poodle and pxa255 corgi.
The patch is included in linux-Yocto since 3.14.

The evident error is the absence of the touchscreen and on corgi a total crash.
pxa2xx-spi: probe of pxa2xx-spi.1 failed with error -2

I sent the full logs to the pxa maintainers.
Please let me know if there are any trivial fixes to apply on the top
of this patch for the non-pci, non-DT boards or better workarounds.

Thanks

Andrea
