For detailed coresight topology, Hi6220 has 8xCA53 CPUs and each CPU has one Embedded Trace Macrocell (ETM); the CPU trace data is output to the cluster funnel. 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 nodes.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
