Address Map Support
The PPC405EP incorporates two address maps. The first address map defines the possible use of
addressable memory regions that the processor can access. The second address map defines Device
Configuration Register (DCR) addresses (numbers). The DCRs are accessed by software running on the
PPC405EP processor through the use of mtdcr and mfdcr instructions.

Notes:
1. When 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.
