I would certainly be happier if it could just be moved into the
firmware or boot loader all the time. The only times we actually
want to do this stuff in the kernel is when we can't trust the
boot loader to get it right, or when the kernel has to support
alternative configurations that the boot loader is not aware of,
e.g. when you can plug in different kinds of extension boards but
the boot loader doesn't know which one you have.
