I support the idea of an 'EFIbus'; but rather than define an address space, I
would prefer to see something more like: !DS0, !DS1..., A0, A1, A2, A3. 
Here, each !DSx would be device select lines that mapped into an address 
space of 16 (through the address lines A0-A3). Each CPU design could map the
!DSx lines into any locations. The hardware would not care where in the CPU
memory map (or I/O map) that it was located; just that it was selected.
