Multiprocessor configuration

It is that simple - at least as far as the hardware is concerned.

You may have issues getting the code loaded, and you might want separate control over the cpu resets (ie add the cpu soft reset as well as the sopc reset).

For instance the boot sequence for cpu 'a' could copy the code & static data for cpu 'b' from flash into any on chip memory before releasing 'b's reset.

Of course, any communication between the two needs proper synchronisation.
