E.g.: for a Register(): the AddressSpace, BitWidth, ... - The penultimate parameter is a NameOpNode. The resource data created is appended to the ResourceTemplate() contained in the NameOpNode. - The last parameter is a pointer holding the created resource data. A least one of the two last parameter must be provided. One of them can be omitted. This generic interface allows to either: - Add the resource data to a NameOpNode. This is a common case for the Ssdt tables generator. - Get the created resource data and let the caller place it in an AML tree.
