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.
