2 * RTEMS monitor IO (device drivers) support
3 *
4 * There are 2 "driver" things the monitor knows about.
5 *
6 *    1. Regular RTEMS drivers.
7 *         This is a table indexed by major device number and
8 *         containing driver entry points only.
9 *
10 *    2. Driver name table.
11 *         A separate table of names for drivers.
12 *         The table converts driver names to a major number
13 *         as index into the driver table and a minor number
14 *         for an argument to driver.
15 *
16 *  Drivers are displayed with 'driver' command.
17 *  Names are displayed with 'name' command.
