+ * 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.
