About which Freescale platform are you talking? I've tried using the patches for the Freescale i.MX6 some month ago. I've managed to get the nodes like below, too. But never managed to get the ETM tracing data into the ETB. Only with attached HW JTAG debugger trace data has been recorded. And I never figured out which additional configuration the HW JTAG is doing compared to the SW only solution.
