Subject: [PATCH 10/11 v6] coresight: adding basic support for Vexpress TC2
From: Mathieu Poirier <mathieu.poirier@...aro.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.
Signed-off-by: Mathieu Poirier <mathieu.poirier@...aro.org>
