By the way, Grant, you seem to be very expert in making a kernel with
ARCH=powerpc. Can you tell me how to find some docs to improve my
knowledge in this field? I've found something interesting in
Documentation/powerpc, but they are not too explicative about the
differences between PPC/Powerpc building, and about how to make the
last one.
