coresignt etm/etb usage

[Zhi Li]

mathieu:

I try to enable etm/etb in our freescale platform.
I have ported your patches into our tree.
coresign node already created in /sys/devices.

30041000.funnel  31001000.interrupt-controller  platform       software
3007c000.etm     backlight.7                    regulators.10  system
3007d000.etm     breakpoint                     replicator.1   timer.0
30084000.etb     gpio-keys.9                    soc.2          virtual
30087000.tpiu    max7322-reset.8                soc0


But my problem is how to test it.
Do you have document to show how to use it?
