I don't have a strong opinion regarding where this driver should
live (I even considered putting it in drivers/bus) :-).
But note that there are other "external memory interface" drivers
in drivers/memory too: TI AEMIF and Marvell DEVBUS  ;-).

Does anyone else think this driver should go in drivers/bus ?

I think drivers/memory is better.

I don't mind if it's drivers/bus or drivers/memory. But I'm 
wondering: When is a driver a bus driver when it is a memory
driver? See imx-weim and atmel-ebi. Apparently both add support
for devices attached on a bus which can be accessed through memory
addresses.

I think drivers/memory should be used for external buses with an
SRAM or DRAM interface that need to configure the timings.

drivers/bus is more a collection for random other buses, usually
internal to a chip, but it's less well-defined.
