43  * The mc-amd driver exports an nvlist to userland, where the primary
44  * consumer is the "chip" topology enumerator for this platform type which
45  * builds a full topology subtree from this information.  Others can use
46  * it, too, but don't depend on it not changing without an ARC contract
47  * (and the contract should probably concern the topology, not this nvlist).
48  *
49  * In the initial mc-amd implementation this nvlist was not versioned;
50  * we'll think of that as version 0 and it may be recognised by the absence
51  * of a "mcamd-nvlist-version member.

54  * that member is optional (only present if the actual value is valid).
