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

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