/* ------------------------------------------------------------------------
 * Modification History: /sys/vaxbi/bireg.h
 *
 * 12-11-87	Robin L. and Larry C.
 *	Added portclass support to the system.
 *
 * 11-Mar-87 -- map
 *                      Added biinfo structure to bidata. Used for bvp
 *                      locking during adapter reset.
 *
 * 10-Jul-86   -- jaw	added adpt/nexus to ioctl
 *
 * 	5-Jun-86   -- jaw 	add bi noarb define.
 * 	5-Jun-86   -- jaw 	changes to config.
 *
 *	08-May-86 -- lp
 *		     AIE can have two different device types. One says
 *		     functioning TK50 firmware is present while the
 *		     other says its not.
 *
 *	04-Apr-86 -- afd
 *		     Added BIVECSIZE constant; and fixed parentheses in
 *		     SCB_BI_VEC_ADDR.
 *
 * 	05-Mar-86 -- jaw  VAXBI device and controller config code added.
 *		     todr code put in cpusw.
 *
 * 	18-Mar-86 -- jaw  add routines to cpu switch for nexus/unibus addreses
 *		     also got rid of some globals like nexnum.
 *		     ka8800 cleanup.
 *
 * 	04-feb-86 -- jaw  get rid of biic.h.
 *
 *	03-Feb-86 -- jaw  added SCB macros.
 *
 *	26-Oct-85 -- jaw  MMR is really NMR.
 *
 *	03-Sep-85 -- jaw  mod of error interrupts.
 *
 * 	19-Jun-85 -- jaw  VAX8200 name change.
 *
 *	05 Jun 85 -- jaw  cleanup...
 *
 *	20 Mar 85 -- jaw  add support for Vax 8200
