Exactly - "entirely board specific" and "doesn't have any possibility of 
being duplicated on other boards."

Right again - _rare_ corner cases. Whereas we are talking about _all_ SPI 
busses, maybe apart from those, where the controller itself switches CSs 
in a well-defined way, and the driver doesn't need any additional 
information to handle this.
