 That's controlled by the DTB. If you use PL011 as the console and
 also want to use bluetooth, you need to reconfigure that to use
 the AUX uart and reduce its speed as the AUX uart has only a
 tiny FIFO.
 
 If you use the AUX uart for anything you must also fix the ARM clock
 (e.g. with force_turbo=1) as the baudrate is derived from it.
