    This isn't a public function. Don't use it. In fact, I can't even
    find it in the current sources. I believe it was the old-style way to
    map memory.

    : bus_space_map() Need explanation of parameters to allow device memory map.

    Chances are excellent you don't want to use this one either.

    : This is all that I need to get the driver working with the user app.

    bus_alloc_resource() is what I think you want to use.
