CE-NG-DV = CE with 32bit kernel version 4.9
CE-NG = CE with 64bit kernel version 4.9
CE-NG-DV was created because there was no known 64bit DV driver for the AM6+/U22XJ 10months ago. Now there is a 64bit driver, and a special 32bit branch no longer needs to be maintained. The same DV code from CE-NG-DV is also in CE-NG.
