cee515d864 Revert "Machine-specific address maps and generic MMIO devices." 2019-08-07 18:33:00 -07:00
Maxim Poliakovski
6ad38c9142 ppcmemory now uses machine's physical address map. 
Hardcoded addresses haven't been completely removed yet. It can be
done after creating proper MMIO devices they're bound to.

9c0c1da53f Replace '&&' with '&' where bitwise AND is expected. 
This fixes compilation warnings when using GCC/Clang.
Improve formatting along the way.
