New Revision: 239668
URL: http://svn.freebsd.org/changeset/base/239668

Log:
  In the gxemul console, check the RB_SERIAL boot flag, and change the
  relative priority of the gxemul console in line with its role as a
  "seiral console".  This allows it to override video console drivers
  that might otherwise take precdence, subject to that boot flag.
