It is not truly a policy. It is a convenience which can be ignored
if so desired. Though I do agree that cpu and board environment variables
would also be useful. Still, a cpu variable would still require
some scripting to combine the quad/dual, duallite/solo. So, your
way is not as convenient for dtb file names.
