/*
* 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 accommodate 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.
