Due system has another CPU and one MCU, all of them transfer the trace data through trace bus (ATB) to SoC funnel; the SoC funnel is connected to Embedded Trace FIFO (ETF) with 8KB buffer; an non-configurable replicator is used to output trace data for two sinks, one is Embedded Trace Route (ETR) so trace data can be saved into DRAM, another is Trace Port Interface Unit (TPIU) for capturing trace data by external debugger. According to the Hi6220 coresight topology, this patch is to add coresight dt binding.
