Grepping all I found was board/mpl/common/isa.c which seems to do something similar. However calling this a driver is quite generous - all it does it write some board-specific values to some registers. So there's really not much to be shared.
Thanks, Paul

Dear Paul Burton,
On a real Malta the Super I/O needs to be configured before we are able to access the UARTs. This patch performs that configuration, setting up the UARTs in the same way that YAMON would.

Do we not already have some kind of a superIO controller driver in U-Boot ? Just wondering, I seem to remember seeing a few. Is this driver re-usable by other boards too maybe?
