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 Techni-
cal Architecture Manual.
The 32-bit physical address space is mapped as follows:
