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

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