The common boot code in the kernel has not been ported to e500 or 85xx. Thus the lack of proper serial support for the 8560. I would recommend using u-boot as the boot loader. U-boot already has support for the 8560 and several boards. - kumar ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
