Update of /cvsroot/gc-linux/linux/arch/powerpc/platforms/embedded6xx
In directory sc8-pr-cvs2.sourceforge.net:/tmp/cvs-serv5134/arch/powerpc/platforms/embedded6xx

Added Files:
	wii.c wii_dev.c 
Log Message:
Added wii platform, specifically.
The platform now:
- uses flipper-pic
- uses device tree for configuration settings
- populates platform devices from device tree instead of drivers
