Computers built with Hitachi SuperH processors always

map the ROM starting at address zero. But the processor

does not specify the range that RAM takes.

The physical memory (RAM) start address will be automatically

set to 08000000. Other platforms, such as the Solution Engine

boards typically map RAM at 0C000000.

Tweak this only when porting to a new machine which does not
