Arnd,

I don't think you're _thinking_.  If you issue 'make uImage', how is the
kernel configuration stuff to know that it should not enable multiple
platforms which would make building a uImage technically impossible
(and lead to the created uImage being non-bootable on some of those
platforms.)

The answer is: you can't.

The best we can do is if the configuration encounters this problem, then
fail to build a uImage.  If that concerns you, then don't ask the kernel
to build an inherently fragile boot loader format in the first place.
