Ahh, my question wasn't clear.  The intended question was, which of 
these properties are new OF (IEEE-1275) or "existing linux kernel" 
*properties* (I didn't intend to ask which are new capabilities).

For instance, how to specify an address already exists, obviously, but I 
suspect a property "data load address" is new.

The intent behind the question was thinking about how big of a 
documentation job this will be.
