The CoreSight support added for Juno is valid for only Juno r0. The Juno r1 and r2 variants have additional components and alternative connection routes between trace source and sinks.
The CoreSight infrastructure external to the Cortex-Axx clusters, has been split into separate .dtsi include files for r0 and r1/r2 to correctly represent these variations.
