| help |
| Enables support for CoreSight tracing. This uses CoreSight trace |
| components and buses to support both hardware (eg. processor ETM) |
| and hardware assisted software instrumentation based (eg. STM) |
| tracing. |

| For production builds, you should probably say 'N' here to avoid |
| potential power, performance and memory penalty. |
