STM is used for logging useful softevens from various entities.
With STM and TMC sink enabled, there will be more buffer size to store
the logs. STM source and STM protocol need to be configured along with
STM device for STM function refer to Documentation/trace/stm.rst.
CONFIG_CORESIGHT_STM is already added as module. Add Coresight STM
source and Protocol configs as module so that STM functions can be
used.

Gentle reminder for the review.

No need to ping for this. It's pending deliberately - on you. If you
want this to be merged, you need to funnel it through SoC maintainer's
tree. get_maintainers.pl (explained also in SoC maintainer profile).

To be clear: I do not object this patch, but I also do not see that many
benefits in having it in defconfig, thus no ack from me.


Best regards,
