/*

 * RTEMS monitor driver names support.

 *

 * There are 2 "driver" things the monitor knows about.

 *

 *    1. Regular RTEMS drivers.

 *         This is a table indexed by major device number and

 *         containing driver entry points only.

 *

 *    2. Driver name table.

 *         A separate table of names for drivers.

 *         The table converts driver names to a major number

 *         as index into the driver table and a minor number

 *         for an argument to driver.

 *

 *  Drivers are displayed with 'driver' command.

 *  Names are displayed with 'dname' command.
