Hi, this PR adds support for SystemView. It introduces tracing API as an abstraction layer. To test this: 1. Download Segger's SystemView app from their website 2. Copy the description file from sys/sysview/SYSVIEW_Mynewt.txt to the /description/ directory of SystemView, e.g. "/opt/SEGGER/SystemView/Description/" 3. Build target with OS_SYSVIEW: 1 4. Launch app and start recording events
Comments are welcome BR, Michał
