I have to deal with a similar problem here: The Dolphin PCI-SCI
adapter. The chip was designed for SBUS first, and it needs all data
This is exotic however, and not enough reason to bloat the bus.h
interface for imho.
I thought about options to the bus space mapping functions at some
time. It's hard to find a sufficient abstraction for all the swapping
