    Cheat Sheet: Cacheable Address Space

- Symptoms:

    Various messages and/or dump output may refer to a physical
    address in the system (i.e., AFAR registers).
            

- Troubleshooting:

    The table below explains the cacheable address range in the
    12K/15K.

       Used with transactions RTO, RTS, WB, RS, and WS

    In general, the address 43 bit address is broken down as follows:

       [42]         0 = cacheable; 1 = non-cacheable
       [41:37]      Memory slice #
       [36:6]       128GB Space
       [5:0]        Offset in line
