/*

* 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.
