/*

 * sercons.c

 *      choose the right serial device at boot time

 *

 * triemer 6-SEP-1998

 *      sercons.c is designed to allow the three different kinds

 *      of serial devices under the decstation world to co-exist

 *      in the same kernel.  The idea here is to abstract

 *      the pieces of the drivers that are common to this file

 *      so that they do not clash at compile time and runtime.

 *

 * HK 16-SEP-1998 v0.002

 *      removed the PROM console as this is not a real serial

 *      device. Added support for PROM console in drivers/char/tty_io.c

 *      instead. Although it may work to enable more than one

 *      console device I strongly recommend to use only one.
