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.
Author:
David N. Cutler (davec) 27-Apr-1991
Revision History:
10-May-1992 John DeRosa [DEC]
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.
31-March-1993 Bruce Butts [DEC]
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.
