Chunyan Zhang (2):
Trace log handler for logging into STM
Adding the function 'trace_event_stm_output_##call' for printing events

This patch also added a function call at where the events have been
committed to ring buffer to export the trace event information to
STM blocks.

Is sdhost based on SDHCI controller?
Why don't use sdhci.c? Is there any reason?

to be a translation from VPID to PID, as such ETM drivers will write the
