| 4 | Enables support for CoreSight tracing. This uses CoreSight trace |
| 5 | components and buses to support both hardware (eg. processor ETM) |
| 6 | and hardware assisted software instrumentation based (eg. STM) |
| 7 | tracing. |

| 9 | For production builds, you should probably say 'N' here to avoid |
| 10 | potential power, performance and memory penalty. |

| 16 | Turns on CoreSight STM tracing (hardware assisted software |
| 17 | instrumentation based tracing) by default. Otherwise, tracing is |
| 18 | disabled by default but can be enabled via sysfs. |
