  17  * Junk Bus Address Space
  18  *   The junk bus is used to access the PROM, LED's, and UART. It's
  19  *   accessed through the local block MMR space. The data path is
  20  *   16 bits wide. This space requires address bits 31-27 to be set, and
  21  *   is further divided by address bits 26:15.
  22  *   The LED addresses are write-only. To read the LEDs, you need to use
