 * 06-Jun-1990	Pete Keilty
 *	1. Modified xmi_reg padding to 17k a must for CIKMF(dash).
 *	2. Added XMI_CIKMF for preliminary support.
 *
 * 11-Apr-1990  Joe Szczypek
 *      Added dtype defines for XMP processor, XBI+ adapter, and XMA2.
 *
 * 08-Dec-1989	Pete Keilty
 *	1. Modified xmi_reg padding to 16k a must for CIXCD.
 *	2. Added 4 new defines for XMI_LEVEL14, XMI_LEVEL15, XMI_LEVEL16
 *	   & XMI_LEVEL17.
 *	3. XMINODE_SIZE is now 16k for VAX.
 *
 * 08-Dec-1989	jaw
 * 	device change for rigel.
 *
 *   19-Sep-1989	Pete Keilty
 *	Add XCD support, remove XCB.
 *
 * 20-Jul-89	rafiey (Ali Rafieymehr)
 *	Added support for XMI devices.
 *
 *   03-May-1988	Todd M. Katz
 *	1. Define XMI device type register fields.
 *	2. Add support for the CIXCB XMI to CI communications port by
 *	   adding the XMI device type XMI_CIXCB.
 *	3. Add placeholder macros for SCB_XMI_LWOFFSET() and
 *	   SCB_XMI_VEC_ADDR().
