247	* The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD
248	* can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to
249	* the LOCAL/current NODE. REMOTE means it is attached to a different
250	* node.(TBD - Need a way to treat ROUTER boards.)
251	*
252	* There are 2 different structures to represent these boards -
253	* lboard - Local board, rboard - remote board. These 2 structures
254	* can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
255	* Figure below). The first byte of the rboard or lboard structure
256	* is used to find out its type - no unions are used.
257	* If it is a lboard, then the config info of this board will be found
258	* on the local node. (LOCAL NODE BASE + offset value gives pointer to
259	* the structure.
260	* If it is a rboard, the local structure contains the node number
261	* and the offset of the beginning of the LINKED LIST on the remote node.
262	* The details of the hardware on a remote node can be built locally,
263	* if required, by reading the LINKED LIST on the remote node and
264	* ignoring all the rboards on that node.
265	*
266	* The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
267	* First board info on the remote node. The remote node list is
268	* traversed as the local list, using the REMOTE BASE ADDRESS and not
269	* the local base address and ignoring all rboard values.

297	*
298	* Each BOARD consists of COMPONENTs and the BOARD structure has
299	* pointers (offsets) to its COMPONENT structure.
300	* The COMPONENT structure has version info, size and speed info, revision,
301	* error info and the NIC info. This structure can accommodate any
302	* BOARD with arbitrary COMPONENT composition.
303	*
304	* The ERRORINFO part of each BOARD has error information
305	* that describes errors about the BOARD itself. It also has flags to
306	* indicate the COMPONENT(s) on the board that have errors. The error
307	* information specific to the COMPONENT is present in the respective
308	* COMPONENT structure.
309	*
310	* The ERRORINFO structure is also treated like a COMPONENT, ie. the
311	* BOARD has pointers(offset) to the ERRORINFO structure. The rboard
312	* structure also has a pointer to the ERRORINFO structure. This is
313	* the place to store ERRORINFO about a REMOTE NODE, if the HUB on
314	* that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
315	* only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
316	* be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
317	* which is present on the REMOTE NODE.(TBD)
318	* REMOTE ERRINFO can be stored on any of the nearest nodes
319	* or on all the nearest nodes.(TBD)
320	* Like BOARD structures, REMOTE ERRINFO structures can be built locally
321	* using the rboard errinfo pointer.
322	*
323	* In order to get useful information from this Data organization, a set of
324	* interface routines are provided (TBD). The important thing to remember while
325	* manipulating the structures, is that, the NODE number information should
326	* be used. If the NODE is non-zero (remote) then each offset should
327	* be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
328	* This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
329	*
330	* Note that these structures do not provide much info about connectivity.
331	* That info will be part of HWGRAPH, which is an extension of the cfg_t
332	* data structure. (ref IP27prom/cfg.h) It has to be extended to include
333	* the IO part of the Network(TBD).
334	*
335	* The data structures below define the above concepts.
