  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.
