Mathieu Poirier 66c6e1177c coresight: tmc: waiting for TMCReady bit before programming ... According to the TRM before programming the TMC in circular buffer mode (and that for any configuration, ETB, ETR, ETF), the TMCReady bit in the status register has to be set. This patch adds a check to make sure the state machine is in a state where it can be configured, and complains otherwise.
