Just ask to post it on penguinppc.org.  There is an embedded section
there.....but why do you want to post something like this?  I mean,
we don't post any of the other drivers or code we do anywhere but in
the sources themselves.

Keep in mind that SPI designs are very dependent upon the board/product
design.  Many of the systems that use SPI have external hardware for
device selection and control.  The generic driver is suitable for clocking
bits in/out but often isn't sufficient to make everything work.  Due to the
timing of SPISEL, I sometimes had to just write a software bit-toggle function
to make it work.
