[RFC PATCH 00/19] powerpc: nintendo gamecube and wii support

[Albert Herranz <albert_herranz@yahoo.es>]

The following patches add the base support for the Nintendo GameCube
and Wii video game consoles on the powerpc arch.

For each video game console, the following is included:
- a device tree source
- bootwrapper support
- udbg console option
- early udbg console option
- interrupt controller support
- platform support

The Nintendo Wii patches also include support for:
- recognition of the broadway processor
- ipc communication with the open source 'mini' firmware replacement

With these patches both video game consoles can fully boot up to the
root filesystem mount phase.
