| /* |
| * 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. |
