[PATCH 10/11 v6] coresight: adding basic support for Vexpress TC2

mathieu.poirier
2014-09-11T15:50:03Z

From: Mathieu Poirier <mathieu.poirier@linaro.org>

Support for the 2 PTMs, 3 ETMs, funnel, TPIU and replicator
connected to the ETB are included. Proper handling of the
ITM and the replicator linked to it along with the CTIs
and SWO are not included.
