Probably. It's hard for me to verify since the SDK is behind a registration/pay wall. CONFIG_TRACEPOINT is a boolean config option so I guess adding CONFIG_TRACEPOINT=y would do the trick. Keep in mind that you will have to rebuild your platform's kernel. Perhaps someone can spot something more obvious?
