It may be general purpose, but how it is hooked up to the host is not and probably could be done in a variety of ways. I'd expect that to be described in a binding doc (that's not a suggestion to add it to this doc as I'm fundamentally against any binding with "UIO" in it). Also, while the processor itself is general purpose, typically its function on a given board would not be except maybe on dev boards. It's that function (a combination of the uC and its firmware) which we want to describe to the host OS. There's already examples of uC used as PMICs or system controllers.

The stm32f100 is a general purpose micro controller. Document a binding that allows a user-space driver to be implemented for these devices.
