Odd.  I don't have a 440SPe, so no surprise there but I would have thought
someone would notice.  Though this is only needed if you are using an older
U-Boot that needs cuImage, and I'm guessing Stefan runs u-boot.git on his
boards ;)

You couldn't be bothered to fixup the typo?  s/beed/need ;)  I'll fix it when
I bring this in.
