The new code is exactly the same as the existing image_get_kernel() and
image_get_ramdisk(). Are those wrong? I wouldn't want to fix my patch to
conform to some supposed standard when the existing code that's been
accepted doesn't conform to that standard, or would I be responsible for
fixing up that too?

But anyway, I imagine there's no point discussing this patch further,
because its sole purpose is to support the uImage load_address=-1 patch
that follows, and it's pretty clear that won't be accepted, so please
consider this patch series withdrawn too.
