   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
   21   sink.
   22 
   23   The CoreSight Address Translation Unit (CATU) translates addresses between an
   24   AXI master and system memory. The CATU is normally used along with the TMC to
   25   implement scattering of virtual trace buffers in physical memory. The CATU
   26   translates contiguous Virtual Addresses (VAs) from an AXI master into
   27   non-contiguous Physical Addresses (PAs) that are intended for system memory.
