Put the whole 24MB here, probe the framebuffer address and size
in the platform code?

This isn't an interrupt controller, don't put #interrupt-cells
here.

XFB address isn't fixed on the hardware, and the kernel might
want to move it, and you can easily probe for it anyway.  Remove
these last two properties please.

These two have the same address, not good.  Just remove the
auxram node?

I always thought optical discs are spelled with a "c", but
people disagree a lot on this :-)

...and all the applicable things I mentioned in my Wii dev tree
reply, of course.

Wow, it wasn't as bad as I expected actually.  But you cheated,
you omitted most devices from the device trees :-)
