+ * Hold common code supporting the ARM7 and ARM9 core generations.
+ *
+ * While the ARM core implementations evolved substantially during these
+ * two generations, they look quite similar from the JTAG perspective.
+ * Both have similar debug facilities, based on the same two scan chains
+ * providing access to the core and to an EmbeddedICE module. Both can
+ * support similar ETM and ETB modules, for tracing. And both expose
+ * what could be viewed as "ARM Classic", with multiple processor modes,
+ * shadowed registers, and support for the Thumb instruction set.
+ *
+ * Processor differences include things like presence or absence of MMU
+ * and cache, pipeline sizes, use of a modified Harvard Architecure
+ * (with separate instruction and data busses from the CPU), support
+ * for cpu clock gating during idle, and more.
