Yup. We just need a bit more wrapped around this. Ie, bringing it
in/out of the SPI mode.

The other question is how we implement it. You've implemented a "get
block" device method. That's a very atheros chipset specific hack just
to get accelerated flash IO. Is there perhaps a better way to approach
this?

What about the 8 versus 32 bit shifting that I see in the driver? Are
we able to actually shift 32 bits at a time?
