[RFC PATCH v2 00/11] powerpc: nintendo gamecube support

[Albert Herranz]

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

The following is included:
- a device tree source
- bootwrapper support
- udbg console option
- early udbg console option
- interrupt controller support
- platform support

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

These patches are a pre-requisite for the patchset supporting the
Nintendo Wii video game console, which will be posted separately
to simplify the review and possible merging.
