My words. ;-) See
http://ozlabs.org/pipermail/linuxppc-dev/2007-August/040685.html
Also, see how it was made initially:
http://ozlabs.org/pipermail/linuxppc-dev/2007-August/040440.html
par_io was in the device tree. But Kumar and Segher convinced me to
not do that.

To my personal taste that's bad idea. In that scheme, I need to upgrade
bootloader to use such a little thing as SPI from the kernel.
I expect very few things from the bootloader: setup memory controller,
copy kernel from the source (flash, ethernet, rs232, ide, sata, ...)
into the RAM and boot it. Everything else from the bootloader side is
profusion.
p.s. Cc'ing Kumar.
