And that is a _very_ bad thing.  The IP is claiming to be created by ARM,
but it isn't - that probably puts this PL011 in a sticky situation from a
legal point of view.  (We've had a CPU which identified itself as an ARM
Ltd ARM926, but it wasn't - the silicon vendor was forced to re-spin their
silicon to change the ID... I wouldn't be surprised if that happens here
too.)
