/*
 * SN0 (on a T5) Address map
 *
 * This file contains a set of definitions and macros which are used
 * to reference into the major address spaces (CAC, HSPEC, IO, MSPEC,
 * and UNCAC) used by the SN0 architecture.  It also contains addresses
 * for "major" statically locatable PROM/Kernel data structures, such as
 * the partition table, the configuration data structure, etc.
 * We make an implicit assumption that the processor using this file
 * follows the R10K's provisions for specifying uncached attributes;
 * should this change, the base registers may very well become processor-
 * dependent.
 *
 * For more information on the address spaces, see the "Local Resources"
 * chapter of the Hub specification.
 *
 * NOTE: This header file is included both by C and by assembler source
 *	 files.  Please bracket any language-dependent definitions
 *	 appropriately.
 */

/*
 * Some of the macros here need to be casted to appropriate types when used
 * from C.  They definitely must not be casted from assembly language so we
 * use some new ANSI preprocessor stuff to paste these on where needed.
 */

/*
 * The following couple of definitions will eventually need to be variables,
 * since the amount of address space assigned to each node depends on
 * whether the system is running in N-mode (more nodes with less memory)
 * or M-mode (fewer nodes with more memory).  We expect that it will
 * be a while before we need to make this decision dynamically, though,
 * so for now we just use defines bracketed by an ifdef.
