- * Junk Bus Address Space
- * The junk bus is used to access the PROM, LED's, and UART. It's
- * accessed through the local block MMR space. The data path is
- * 16 bits wide. This space requires address bits 31-27 to be set, and
- * is further divided by address bits 26:15.
- * The LED addresses are write-only. To read the LEDs, you need to use
- * SH_JUNK_BUS_LED0-3, defined in shub_mmr.h
