16  * SN0 (on a T5) Address map
17  *
18  * This file contains a set of definitions and macros which are used
19  * to reference into the major address spaces (CAC, HSPEC, IO, MSPEC,
20  * and UNCAC) used by the SN0 architecture.  It also contains addresses
21  * for "major" statically locatable PROM/Kernel data structures, such as
22  * the partition table, the configuration data structure, etc.
23  * We make an implicit assumption that the processor using this file
24  * follows the R10K's provisions for specifying uncached attributes;
25  * should this change, the base registers may very well become processor-
26  * dependent.
27  *
28  * For more information on the address spaces, see the "Local Resources"
29  * chapter of the Hub specification.
30  *
31  * NOTE: This header file is included both by C and by assembler source
32  *	 files.	 Please bracket any language-dependent definitions
33  *	 appropriately.
34  */
35 
36 /*
37  * Some of the macros here need to be casted to appropriate types when used
38  * from C.  They definitely must not be casted from assembly language so we
39  * use some new ANSI preprocessor stuff to paste these on where needed.
40  */
41 
42 /*
43  * The following couple of definitions will eventually need to be variables,
44  * since the amount of address space assigned to each node depends on
45  * whether the system is running in N-mode (more nodes with less memory)
46  * or M-mode (fewer nodes with more memory).  We expect that it will
47  * be a while before we need to make this decision dynamically, though,
48  * so for now we just use defines bracketed by an ifdef.
