 |  * 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. |
