It just needs to be part of the bus logic for the specific bus that this "firewall" is on. Just like we do the same thing for USB or thunderbolt devices. Put this in the bus-specific code please.
I'd expect that this is going to affect at least platform and AMBA buses.
Correct me if I'm wrong but creating a new type of bus would mean
that all the drivers living on this bus must be changed to register themselves on this bus ?
Or does a solution exist to let them live on the platform bus and call firewalled bus before been probed ?
All the impacted drivers could work on the existing bus with or without the firewall so I don't want to break
that.
