Same with me. I cannot understand how maybe-GPL-incompatable 
sources can be part of U-Boot. This file is not the only one.
Also the top level README says that the sources are under the GPL.
So does it even play any role when the GPL lines are not contained in some files?
Isn't it enough to have the licence of the whole project mentioned once?

To be on the legal side, I will keep the GPL note off this file.
Same with me. IANAL. And I am not very motivated to become one sooner or later.
