The project I originally did the 1.18 integration on completed ~2yrs
back and my access to WindRiver Simics material is now gone.  It's too
bad they didn't keep this driver public, however you may check with
your WindRiver Simics contacts to see if they just moved the site and
you could propose an update to this Buildroot package fixing support.
