Gentle ping... Hi Mathieu and Suzuki, can you have a look at this patchset? thanks.
On August 2nd I got back to you privately saying I won't be able to review this patchset before the last week of August or the first week of September. Pinging me again on it won't change that reality.

This patchset add support for SMB(System Memory Buffer) device, SMB obtains CPU instructions from Coresight ETM device and stores these messages in system memory. SMB is developed by Ultrasoc technology, which is acquired by Siemens, and we still use "Ultrasoc" to name document and driver.
Change since RFC:
- Move ultrasoc driver to drivers/hwtracing/coresight.
- Remove ultrasoc-axi-com.c, as AXI-COM doesn't need to be configured in basic tracing function.
- Remove ultrasoc.c as SMB does not need to register with the ultrasoc core.
- Address the comments from Mathieu and Suzuki.
