Thanks Ron. After reading your answer I thought about the fact that there is only one BAR on a bridge for each type of resource, and the split resource idea didn't make as much sense.
yes, and thinking about it ... there's only one bridge anywhere in the system that is going to decode legacy IO, or mem, or vsa (not always same bridge).
I wonder if it would be simpler to have a property to mark these bridges in the dts. It can not be determined -- code has to know that a given piece of hardware is decoding the legacy range.
