218 * The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD
219 * can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to
220 * the LOCAL/current NODE. REMOTE means it is attached to a different
221 * node.(TBD - Need a way to treat ROUTER boards.)
222 *
223 * There are 2 different structures to represent these boards -
224 * lboard - Local board, rboard - remote board. These 2 structures
225 * can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
226 * Figure below). The first byte of the rboard or lboard structure
227 * is used to find out its type - no unions are used.
228 * If it is a lboard, then the config info of this board will be found
229 * on the local node. (LOCAL NODE BASE + offset value gives pointer to
230 * the structure.
231 * If it is a rboard, the local structure contains the node number
232 * and the offset of the beginning of the LINKED LIST on the remote node.
233 * The details of the hardware on a remote node can be built locally,
234 * if required, by reading the LINKED LIST on the remote node and
235 * ignoring all the rboards on that node.
236 *
237 * The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
238 * First board info on the remote node. The remote node list is
239 * traversed as the local list, using the REMOTE BASE ADDRESS and not
240 * the local base address and ignoring all rboard values.

268 *
269 * Each BOARD consists of COMPONENTs and the BOARD structure has
270 * pointers (offsets) to its COMPONENT structure.
271 * The COMPONENT structure has version info, size and speed info, revision,
272 * error info and the NIC info. This structure can accommodate any
273 * BOARD with arbitrary COMPONENT composition.
274 *
275 * The ERRORINFO part of each BOARD has error information
276 * that describes errors about the BOARD itself. It also has flags to
277 * indicate the COMPONENT(s) on the board that have errors. The error
278 * information specific to the COMPONENT is present in the respective
279 * COMPONENT structure.
280 *
281 * The ERRORINFO structure is also treated like a COMPONENT, ie. the
282 * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
283 * structure also has a pointer to the ERRORINFO structure. This is
284 * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
285 * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
286 * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
287 * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
288 * which is present on the REMOTE NODE.(TBD)
289 * REMOTE ERRINFO can be stored on any of the nearest nodes
290 * or on all the nearest nodes.(TBD)
291 * Like BOARD structures, REMOTE ERRINFO structures can be built locally
292 * using the rboard errinfo pointer.
293 *
294 * In order to get useful information from this Data organization, a set of
295 * interface routines are provided (TBD). The important thing to remember while
296 * manipulating the structures, is that, the NODE number information should
297 * be used. If the NODE is non-zero (remote) then each offset should
298 * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
299 * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
300 *
301 * Note that these structures do not provide much info about connectivity.
302 * That info will be part of HWGRAPH, which is an extension of the cfg_t
303 * data structure. (ref IP27prom/cfg.h) It has to be extended to include
304 * the IO part of the Network(TBD).
305 *
306 * The data structures below define the above concepts.

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.

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.
