- * 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 SN1 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 R12K'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
