-/* ETM register access functionality
+
+/*
+ * ARM "Embedded Trace Macrocell" (ETM) support -- direct JTAG access.
+ *
+ * ETM modules collect instruction and/or data trace information, compress
+ * it, and transfer it to a debugging host through either a (buffered) trace
+ * port (often a 38-pin Mictor connector) or an Embedded Trace Buffer (ETB).
*
+ * There are several generations of these modules. Original versions have
+ * JTAG access through a dedicated scan chain. Recent versions have added
+ * access via coprocessor instructions, memory addressing, and the ARM Debug
+ * Interface v5 (ADIv5); and phased out direct JTAG access.
+ *
+ * This code supports up to the ETMv1.3 architecture, as seen in ETM9 and
+ * most common ARM9 systems. Note: "CoreSight ETM9" implements ETMv3.2,
+ * implying non-JTAG connectivity options.
+ *
+ * Relevant documentation includes:
+ * ARM DDI 0157G ... ETM9 (r2p2) Technical Reference Manual
+ * ARM DDI 0315B ... CoreSight ETM9 (r0p1) Technical Reference Manual
+ * ARM IHI 0014O ... Embedded Trace Macrocell, Architecture Specification
