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 'dname' command. |
