+Test: coresight
+
+Usage: cs_test.sh [-n | --nominal] [-a | --adversarial] [-r | --repeatability]\
+       [-s | stress ]
+       Runs the tests for CoreSight trace drivers.
+
+
+Options:
+The following options can be used:
+-n | --nominal                                 nominal test, runs by default
+-a | --adversarial                             adversarial test
+-r | --repeatability iterations                repeatability test, runs 10
+                                               iterations by default
+-s | --stress                                  stress test
+--source trace_source                          trace source, supported
+                                               trace_source values are 'etm'
+                                               and 'stm'
+
+Requirement:
+CoreSight ETM and STM sources are initially disabled before running any test.
+
+Description:
+Nominal Test:
+All CoreSight tests are invoked.
+
+Adversarial Test:
+Runs cs_adversary.sh. This test enables all trace sources, all ftrace events and
+toggles the cpu cores on/off.
+
+Repeatability Tests:
+All test cases except probe test are invoked for user specified number of iterations,
+or for 10 iterations by default.
+
+Stress Test:
+All test cases except probe test are invoked for 100 iterations.
+
+Test case description:
+1. platform/platform.sh
+Tests that CoreSight trace drivers are probed without failures.
+
+2. etm/etm_enable.sh
+Tests ETM tracing gets properly enabled.
+
+3. etm/etm_disable.sh
+Tests ETM tracing get properly disabled.
+
+4. stm/stm_enable.sh
+Tests STM tracing gets properly enabled.
+
+5. stm/stm_disable.sh
+Tests STM tracing gets properly disabled.
+
+6. stm/stm_etf_dump.sh
+Tests ETF can be dumped with good data while STM is the only trace source. All ftrace,
+hardware events are disabled while single string data is sent over STM. Once trailing
+zeros of output file are truncated, size is compared with reference size for same
+input data.
+
+7. stm/stm_etr_dump.sh
+Please refer to stm/stm_etf_dump.sh. Here ETR is the trace sink instead of ETM.
+
+8. mult_trace/mult_source_enable.sh
+Tests that multiple CoreSight trace sources (ETM and STM) can be successfully enabled
+at the same time.
+
+9. mult_trace/mult_source_disable.sh
+Tests that multiple CoreSight trace sources (ETM and STM) can be successfully disabled
+at the same time.
+
+10. sink_switch/sinkswitch.sh
+Tests that the device can switch between multiple CoreSight tracesinks. Assumes etf,
+etr and tpiu sinks are present.
+
+11. sink_switch/etr_modes.sh
+Tests that the modes of ETR can be changed from usb to memory and vice versa.
+
+12. cs_adversary.sh
+While having trace sources enabled, enables and disables all cores in a loop.
+
+Targets supported: 8974
+
+Test output:
+All tests prints:
+"PASS: <message>" if the test case passes
+ or
+"FAIL: <message>" otherwise
+
+Note: Tests assume /data partition exists
