MP tables are a relatively easy problem. The next step could be reusing
the data for PIR (and extending the devicetree model where necessary).

Once our devicetree is suitable for these two, it should also be good
enough for ACPI. That's one thing less to worry about when extending
acpigen.

Hardware doesn't require it, but some software is happier when having
meaningful legacy tables.

yeah, I guess I do too.

Hi all,

Sorry for the delay. I was busy with other stuff recently. I like it, just 
please note that ACPI requires to aggregate the _PRT objects under every PCI 
bridge device.

The root bridge has to have _PRT table (usually it contains routing for BUS 0). 
The other bridges (_PCI devices) contains aggregate _PRT routing entries for bus 
directly behind the bridge.

Plz check src/mainboard/asus/m2v-mx_se/dsdt.asl for details.

Thanks
Rudolf
