Module Name:

  jnsnprom.h

Abstract:

    This module is the header file that describes physical and virtual
    address used by the PROM monitor and boot code in the Alpha PCs.
    Started from \nt\private\ntos\inc\jazzprom.h.

    Made changes for Alpha/Jensen.  With the changes to the Alpha/Jensen
    meta-virtual linear addresses, this file now defines a different
    subset of things than the jazzprom.h file did.  Note that the
    ntos\inc\jnsndef.h file defines a few virtual bases, and those
    bases are not defined here.  Why don't we define the virtual bases
    all in one place?  Don't ask.

    Converted file to QVA macros instead of handcoded QVAs.

// The Alpha PC firmware I/O space routines (READ_PORT_UCHAR, etc.)
// map a quasi-virtual linear address space into EV4 kernel superpages, so that
// physical = virtual.  And, all of the firmware runs in superpage mode as well.
//
// The _PHYSICAL_ addresses in \nt\private\ntos\inc\jnsndef.h and mrgndef.h
// are real physical addresses.  Since the Alpha/Jensen firmware source code
// deals with the quasi-virtual addresses (QVAs), the base symbols that it is
// compiled with are *not* the real physical addresses, but instead the QVA
// addresses.
//
// The virtual/physical pairs are not strictly necessary for Alpha PCs
// since memory mapping is off.  But, since I need QVA addresses for my
// I/O anyway, the _VIRTUAL_ duals are in fact QVA addresses, and this is what
// will be used everywhere in the firmware pointer definitions.
