Hi,

I think it could be a good idea to start documenting the cpu configuration in
the device tree on some of these larger platforms as well, i.e. include a cpus/
hierarchy. Would you mind adding those, please?

It would give you the flexibility of switching over to using device
tree to probe the number of cpus in case the platform grows yet another
way to figure out the number of cores in the future, without having to
update the device-trees at that time. :)
