This enables support for CoreSight link and sink drivers that are
responsible for transporting and collecting the trace data
respectively. Link and sinks are dynamically aggregated with a trace
entity at run time to form a complete trace path.
+ To compile these drivers as modules, choose M here: the
+ modules will be called coresight-funnel and coresight-replicator.
