        if (cpu_init_detected()) {
                asm volatile ("jmp __cpu_reset");

The cpu_init seems reset the memcontroller with opteron. (all HT links
configuration are still there).  So you can not just 
jmp to __cpu_reset.

There are two solution for it
1. init ram and then jump to __cpu_reset
	But the smbus_io_base may already changed by last normal boot. So
should use assigned smbus_io_base, that need to change amd8111_early_smbus.c

2. just issue another soft reset, --- amd8111 is in bus 1 now.

        if (cpu_init_detected()) {
#if 0
                asm volatile ("jmp __cpu_reset");
                /* cpu reset also reset the memtroller ????
            need soft_reset to reset all except keep HT link freq and width

Which one do you prefer to?
