It is still global data, but the const makes it smaller and should
be there if accepted. Like I said, it is just a minor comment as
u-boot isn't ready for full relocation yet.

BTW, what happened to relocation stuff Grant was doing? It is
still disabled, I never had any problems so perhaps time to
turn it on again? it might even make u-boot smaller once all the
old manuel relocation code has been properly disabled.
