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

55  * Version 1 is defined as follows.  A name in square brackets indicates
56  * that member is optional (only present if the actual value is valid).
