Hopefully including any AVR32 boards featuring DataFlash.

Any chance the SPI driver could move into drivers/ as well? The
at32ap7000 has pretty much the same SPI hardware built in, and IMO
there shouldn't really be anything chip-specific about it apart from
pin configuration, register base address and interrupt line (if it
even uses that.)

I'm willing to review the driver if you send it inline as a single
patch, and perhaps help you clean it up as well, if needed. Please Cc
hskinnemoen at atmel.com so I receive it in my mail client at work.

It could have something to do with the tarball submission format not
being particularly reviewer-friendly...
