This driver adds support for the STM CoreSight IP block,
allowing any system compoment (HW or SW) to log and
aggregate messages via a single entity.

The STM exposes an application defined number of channels
called stimulus port.  Configuration is done using entries
in sysfs and channels made available to userspace via devfs.
