     Could you elaborate on this? Completely different drivers
or several instances of the same driver? Use case is welcome. 
dev/spibus is just abstraction that provides interface to child
devices. It can't be machine-specific. Bridge implementation
(at91_spi) is machine specific and implements actual hardware
access.
