Actually now I think about it if we're not going to parse the MPIDR we should probably update the bindings to say that the topology binding is mandatory for any v8 system with more than one core.
Do we need such information if only a flat topology is needed?
Probably not but it's simpler to specify that rather than saying it's mandatory only if you need it and it might be useful to know if everything is a flat collection of threads or a flat collection of cores, it seems better to get the information in there if we can in case the DT is fixed. Single core systems are the only ones where it's definitely never going to be helpful.
