ETM data trace

Hi All,

I remember that Mathieu and Al said that data trace is no longer supported on A profile cores except A7 (i.e. ETMv3). But I noticed that the ETMv3/v4 data trace was mentioned again in README [1] - "Support to be added". What does the "data trace" in [1] refer to. Is it only for the ETMv3/v4 on M / R profile cores?

Thanks, Chunyan
