/*
* 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.
