The Coresight TMC-ETR SG mode could be unsafe on a platform where
the ETR is not properly connected to account for READ operations.
We use a DT node property to indicate if the system is safe.
This patch also provides a command line parameter to "force"
the use of SG mode to override the firmware information.

Hi

This is more of a debug patch for people who may want to
test their platform without too much of hacking. I am not
too keen on pushing this patch in.

I am not either nor do I personally need it to test this feature. We can leave
it in for now (and subsequent version) if you need it but we agree that I won't
queue it to my tree when the time comes.

OK, I was expecting this view from most of us here. I will drop it from my series in
the next version.

Cheers
Suzuki
