Uh.. where are the CPUs?


The number and type of CPUs can be (and is) probed. There is an existing mechanism for the bootloader to communicate which CPUs should be used.

Likewise for memory, there is an existing mechanism for the bootloader to communicate which memory should be used.

It is possible that in the future, we would want to put CPUs and Memory in the Device Tree. If we do, we can add that without having to disturb the 'soc' device bindings.

My main motivation for this first patch set is to get sane bindings for all the 'soc' devices And to that end, your feedback has been quite useful.

Thanks,
David Daney
