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