[U-Boot-Users] [PATCH] Fixed reset for syscon3

[HarryCheng <zheharry@gmail.com>]

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.

For your reference. BRs
