Lorenzo (on holiday now) pushed the DT topology bindings but there are no patches yet for reading them. I would much prefer to only describe the topology via DT rather than MPIDR (because hardware people sometimes have strange ideas).
Topology code for ARM32 is based on MPIDR now, should we update it too with describing the topology via DT?
Yes, the binding is supposed to apply to both so it'd be good to support it on pre-v8. However using MPIDR should continue to be supported on pre-v8 as existing systems don't use the topology binding and so presumably have accurate MPIDRs, requiring the binding would be a regression for them.
