This enables support for the Embedded Trace Buffer version 1.0 driver
that complies with the generic implementation of the component without
special enhancement or added features.

select CORESIGHT_LINKS_AND_SINKS
help
This driver provides support for processor ETM3.x and PTM1.x modules,
which allows tracing the instructions that a processor is executing
This is primarily useful for instruction level tracing. Depending
the ETM version data tracing may also be available.
