I don't understand why this is needed.  CONFIG_LMB should be set so
image_setup_linux will be called which will call image_setup_libfdt
which will call fdt_fixup_ethernet along with other stuff we'd want done
as well.  I suspect we have some bug somewhere along the line with
regards to pre ARMv7 platforms and FDT where some knob or another that
should be set, is not set.
