The documentation I'm using is from the ARM developer site I think. I don't *think* I can provide a link since it's behind a login page? Not sure if it was or if I could, but it should be fairly easy to find. The two documents I'm using primarily are the reference manual and user guide. I don't think either list what resources each model provides, but I have such a list I read from the model programmatically and then printed out.
That said, if the model isn't expected to have those registers since it doesn't have SVE, then that explains why they aren't there :-). I'll plumb up dummy registers which just satisfy the interface and don't have any connection to the fast model.
