15 * The KLCONFIG structures store info about the various BOARDs found
16 * during Hardware Discovery. In addition, it stores info about the
17 * components found on the BOARDs.
22 * Certain assembly language routines (notably xxxxx.s) in the IP27PROM
23 * will depend on the format of the data structures in this file. In
24 * most cases, rearranging the fields can seriously break things.

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

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