13 * \author Giovanni Bajo <rasky@develer.com>
18 *#* Revision 1.6 2005/04/11 19:10:27 bernie
19 *#* Include top-level headers from cfg/ subdir.
21 *#* Revision 1.5 2004/08/25 14:12:08 rasky
22 *#* Aggiornato il comment block dei log RCS
24 *#* Revision 1.4 2004/07/30 14:15:53 rasky
25 *#* Nuovo supporto unificato per detect della CPU
27 *#* Revision 1.3 2004/07/14 14:04:29 rasky
28 *#* Merge da SC: spostata bld_set inline perché si ottimizza parecchio tramite propagazione di costanti
30 *#* Revision 1.2 2004/06/03 11:27:09 bernie
31 *#* Add dual-license information.
33 *#* Revision 1.1 2004/05/23 18:36:05 bernie
34 *#* Import buzzerled driver.
