I think we can all agree that the sysbus bus is not a bus per se. So
conceptually, what's the difference between a device attached to a
non-bus and a device not attached to a bus at all? And why can't we
convert sysbus to not be a bus anymore?

I think there is no difference, and I don't think moving out of sysbus is really a goal that we need to pursue.

I agree with Andreas that having a "SoC object" as father of sysbus (instead of "nothing at all") would be slightly better.

We could also make TYPE_MACHINE a subclass of TYPE_DEVICE, to have an obvious place for this SoC object.
