[U-Boot] representing multi-socket CPU platform in .dts

[Curt Brune]

Hi,

What does u-boot expect to find in the device tree for a system with 
multiple CPU sockets (not multi-core, but multiple physical CPUs) ?

For example if you have a two socket system, with a dual-core CPU per 
socket would there just be 4 nodes in cpus {} with reg = 0, 1, 2, 3 or 
is there a "cpu-socket" node?

Cheers,
Curt
