/* ------------------------------------------------------------------------
 * Modification History: /sys/vaxuba/ubareg.h
 *
 * 03-Aug-90	rafiey (Ali Rafieymehr)
 *	Added a define for VAX9000.
 *
 *  8-May-89  Giles Atkinson
 *    Extend definition of nb4_regs to include console version.
 *
 * 05-Nov-88	Robin Lewis
 *	Changed the defines used to get map register information on
 *	the Q22-Bus.  The format of the "cookie" was changed to allow
 *	more map registers to be allocated on one call.
 *
 * 28-Jun-88	Fred Canter
 *	Modified nb_regs structure to add PVAX system SCSI bus ID.
 *	This allows the SCSI drive to read the system's (initiator)
 *	ID from NVR.
 *
 * 08-Jun-88	darrell for Ali
 *	Added VAX60 (Firefox) support.
 *
 * 07-Jun-88	Fred Canter
 *	Back out last change (hardware changed their mind).
 *
 * 06-Jun-88	Fred Canter
 *	Use different address for SCSI/SCSI controller.
 *
 * 19-May-88    Fred Canter
 *	Modifications for SCSI driver and extended I/O mode
 *	operation of CVAXstarPVAX.
 *
 * 15-Feb-88	Fred Canter
 *	Added support for VAX420 (CVAXstar/PVAX) CPU.
 *	Mostly I/O space register structutes and definitions.
 *
 * 12-11-87	Robin L. and Larry C.
 *	Added portclass support to the system.
 *
 *  3-Aug-87 -- rafiey (Ali Rafieymehr)
 *	Added structure for the VAXstation 2000 system scratch RAM.
 *
 * 20-Apr-87 -- afd
 *	Moved structures for Mayfair local register space to ka650.h
 *
 * 06-Mar-87 -- afd
 *	Defined 5 structures for Mayfair/CVAX local register space;
 *	also defined constants for their addresses and sizes.
 *
 * 07-Jan-87  -- rafiey (Ali Rafieymehr)
 *	Corrected the value for the VAXstar color display option
 *	(VS_CID_COLOR).
 *
 * 13-Dec-86  -- fred (Fred Canter) and rafiey (Ali Rafieymehr)
 *	Change sh and sg maps (address and size).
 * 30-Aug-86  -- fred (Fred Canter)
 *	General cleanup of comments.
 *
 *  5-Aug-86   -- fred (Fred Canter)
 *	Updated VAXstar I/O space register definitions.
 *
 *  2-Jul-86   -- fred (Fred Canter)
 *	Defines for TEAMmate 8 line SLU register mapping.
 *
 * 18-Jun-86   -- fred (Fred Canter)
 *	Changes for VAXstar kernel support.
 *
 * 13-Jun-86   -- jaw 	fix to uba reset and drivers.
 *
 * 14-Apr-86 -- jaw
 *	remove MAXNUBA referances.....use NUBA only!
 *
 * 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.
 *
 * 22-Oct-85 -- tresvik
 *	fixed typo to for VAX8600 conditional
 *
 * 10-sep-85 -- jaw
 *	increased number of UBA's on 8200 from 4 to 10.
 *
 * 31-Jul-85 -- tresvik
 *	Fixed sizing problem for maximum uba's on VAX8600.  Increased 
 *	MAXNUBA and NUBA8600 to 8 to allow proper indexing.
 *
 * 19-Jun-85 -- jaw
 *	VAX8200 name change.
 *
 * 18-Jun-85 -- JAW
 *	fixed up purge macro so machine specific compiles work.
 *
 * 01-May-85 -tresvik
 *	Fix conditionals on UBA register defs so that /sys/stand could build
 *	a 750 only version of autoconf.c
 *
 * 13-Mar-85 -jaw
 *	Changes for support of the VAX8200 were merged in.
 *
 * 27-Feb-85 -tresvik
 *	Changes for support of the VAX8600 were merged in.
 *
 *  3 Nov 84 -- rjl
 *	MicroVAX-II support
 *	The microVAX support stuff should probably be in seperate qbus files
 *	but at this time is so close that it hardly seems to make much sense.
 *
 * 29 Dec 83 --jmcg
 *	MicroVAX I support.
 *
 * 28 Dec 83 --jmcg
 *	Derived from 4.2BSD, labeled:
 *		ubareg.h	6.2	83/09/29
