What do you mean by "real relocation"? As per start.S bootcode is
copied from ROM to RAM.

However, this is possible if only startup code is in NOR flash.

Usually one ports U-Boot on a board with predefined hardware layout,
i.e. flash, SDRAM and peripherals are fixed. If hardware changes, say
SDRAM size, no big deal to make two/three distinct u-boot images --
after all it ends up by changing TEXT_BASE only, as I understand.
