I don't think CFE relocates U-Boot because the main purpose is to boot
kernels where only recent ones can be relocated. CFE's tasks should only
be to copy the ELF payload to the link address specified in ELF header,
to invalidate I-Caches and to jump to that address.
I'd rather think the appended DTB is either not correctly linked in
the ELF binary or not copied by CFE. The address of the appended DT blob
is determined with the linker symbol "_end". If CFE would relocate, this
symbol would also point to the relocated memory address.
