And you just broke split bridge setups. Also need to check if the bits are valid for this chipset in native mode officialy - Sergei probably knows the answer to that.
The PCI-649 spec. doesn't say anything about legacy/native mode WRT the channel enable bits.
We can detect the Mobility electronics split bridges at least (and I suspect they are the only 'common' CMD64x hot plug device indeed possibly the only one) because the parent bridge of the CMD64x will have a PCI vendor id of 0x14f2 and a device id 0x0001, 0x0002, or 0x0120.
What's the issue with these brodges anyway? Why the enable bits are not valid for them?
