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.
