The system bus is implemented as a bus matrix. All system bus addresses are fixed, and they
are never remapped in any way, not even in boot. Note that AVR32 UC CPU uses unsegmented
translation, as described in the AVR32UC Technical Architecture Manual. The 32-bit physical
address space is mapped as follows:
