Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Most affect comments, very few have user-visible effects.

functional change.

[1]	Add the support for the NARK controller which seems a variant of
	the i960Rx.
[2]	Split up memory regions and other resources in 2 different parts
	as long as NARK uses them separately (it is not clear to me
	why though as long as there are no more informations available
	on this controller). Please note that in all the other cases,
	the regions overlaps leaving the default behaviour for all the
	other controllers.
[3]	Implement a clock daemon responsible for maintain updated the
	wall clock time of the controller (run any 30 minutes)*.

  is not implemented with callouts as in our in-tree driver.
