16 CoreSight components are compliant with the ARM CoreSight architecture
17 specification and can be connected in various topologies to suit a particular
18 SoCs tracing needs. These trace components can generally be classified as
19 sinks, links and sources. Trace data produced by one or more sources flows
20 through the intermediate links connecting the source to the currently selected
23 The Coresight funnel merges 2-8 trace sources into a single trace
24 stream with programmable enable and priority of input ports.
