I don't think it's a good idea to allow external drivers to
tinker directly with GPMC registers. How about just set up GPMC
as an irqchip for the edge detection interrupts?
I think we already have devices with multiple NAND chips. And
there's nothing stopping other drivers from using the edge
detection interrupts.

Tony
