Add base support for the AMCC PowerPC 405EZ Acadia evalution board. In addition
to some of the normal PPC 40x peripherals, the Acadia board has:
- 64 MiB PSRAM
- NOR and NAND flash
- Two USB 1.1 host ports
- Two CAN 2.0 ports
- ADC and DAC connectors
- LCD display
This adds the basic platform support to build from.
