+/**
+ * @file
+ * This file implements support for the ARM Debug Interface version 5 (ADIv5)
+ * debugging architecture. Compared with previous versions, this includes
+ * a low pin-count Serial Wire Debug (SWD) alternative to JTAG for message
+ * transport, and focusses on memory mapped resources as defined by the
+ * CoreSight architecture.
+ *
+ * A key concept in ADIv5 is the Debug Access Port, or DAP. A DAP has two
+ * basic components: a Debug Port (DP) transporting messages to and from a
+ * debugger, and an Access Port (AP) accessing resources. Three types of DP
+ * are defined. One uses only JTAG for communication, and is called JTAG-DP.
+ * One uses only SWD for communication, and is called SW-DP. The third can
+ * use either SWD or JTAG, and is called SWJ-DP. The most common type of AP
+ * is used to access memory mapped resources and is called a MEM-AP. Also a
+ * JTAG-AP is also defined, bridging to JTAG resources; those are uncommon.
