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.
