On one hand you've got uml, which simply doesn't have mmio. On the other there's mtd, which began as a method for accessing hardware devices that are often accessed using mmio. But then the mtd subsystem developed emulations of that hardware that are software based and thus don't require mmio. It's mainly these emulated backends I'm interested in exposing.
Nothing is going to change so that it makes sense to have any real mmio-using hardware driver run on uml. The question you raise is, are there other classes of driver with a software-only subset that can be exposed on uml? And if so, would adding stub implementations of readb/writeb and friends actually be enough to make those work? I'm not aware of any, so at present I don't think the argument for implementing this in uml arch code is very strong. Or in other words, I don't think a "general solution" would be very general.
