Module Name:

    jnsndef.h

Abstract:

    This module is the header file that describes hardware addresses
    for the Jensen systems.

Author:

    David N. Cutler (davec) 26-Nov-1990
    Miche Baker-Harvey (miche) 13-May 1992

Revision History:

    2-Oct-1992 Rod Gamache [DEC]
      Add DEVICE_LEVEL.

    22-Jul-1992 Jeff McLeman (mcleman)
      Add three define QVA's for DMA control,
      Video memory and video control. These are the
      same addresses the FW wil use, so they can reside
      here. Add INT_CONTROL and VA for INTA.

    12-Jul-1992 Jeff McLeman (mcleman)
      Move PTRANSLATION_ENTRY to jnsndma.h

    07-Jul-1992 Jeff McLeman (mcleman)
      Add PTRANSLATION_ENTRY structure
