The feature of having the possibility to rewrite the dev trees MAC addresses in
ft_board_setup(). Currently such rewrites are overwritten by the call to dt_fixup_ethernet(blob)
in image_setup_libfdt().
Looking into the history I see that commit 13d06981(by you as it happens :) is the one adding
the extra call to fdt_fixup_ethernet()

arch/arm/cpu/armv7/ls102xa/fdt.c:       fdt_fixup_ethernet(blob);
arch/mips/lib/bootm.c:  fdt_fixup_ethernet(images->ft_addr);
arch/nios2/cpu/fdt.c:   fdt_fixup_ethernet(blob);
arch/powerpc/cpu/mpc512x/cpu.c: fdt_fixup_ethernet(blob);
arch/powerpc/cpu/mpc8260/cpu.c: fdt_fixup_ethernet(blob);
arch/powerpc/cpu/mpc83xx/fdt.c: fdt_fixup_ethernet(blob);
arch/powerpc/cpu/mpc85xx/fdt.c: fdt_fixup_ethernet(blob);
arch/powerpc/cpu/mpc86xx/fdt.c: fdt_fixup_ethernet(blob);
arch/powerpc/cpu/mpc8xx/fdt.c:  fdt_fixup_ethernet(blob);
arch/powerpc/cpu/ppc4xx/fdt.c:  fdt_fixup_ethernet(blob);

Seems like it is mostly PPC which has fdt_fixup_ethernet() call though.
