Notes:
1. When external peripheral bus boot is selected, peripheral bank 0 is automatically configured at reset to the address range listed
above.
2. If PCI boot is selected, a PLB-to-PCI mapping is automatically configured at reset to the address range listed above.
3. After the boot process, software may reassign the boot memory regions for other uses.
4. All address ranges not listed above are reserved.
