I have tested coresight with scatter gather on SDM845 MTP and MSM8996
based DB820c board and posted the results in

- https://github.com/saiprakash-ranjan/coresight-test-results

Please let me know if you need some additional testing done.

I could not perform coresight tests on MSM8998 MTP with latest build
as it was resulting in crash due to some AHB timeouts. This was not
due to scatter-gather and mostly likely the problem with the build.
Maybe we can keep msm8998-coresight on hold?

BTW, patches are based on linux-next.

Thanks,
Sai
