I have a customized MPC8548 board with several hardware reset source (to HRESET AG17), and the trigger signal is a GPIO pin instead of the default HRESET_REQ (AG16). the patch simply replaces the HRESET_REQ by the certain pin of GUR registers on both cpu/mpc85xx/cpu.c of the u-boot and arch/powerpc/platforms/85xx/misc.c of the linux.
