I'm afraid, but the "other ppc's" did break with this patch. At least 4xx
does. With your patch applied relocation to SDRAM does not work anymore.
Here's what I get:

CFG_MONITOR_BASE=fffa0000
(ulong)&_start + EXC_OFF_SYS_RESET=fffa2200
EXC_OFF_SYS_RESET=100

I haven't looked into it closer yet. Any idea on how to fix this?

Thanks.

Best regards,
Stefan
