35 * The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD
36 * can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to
37 * the LOCAL/current NODE. REMOTE means it is attached to a different
38 * node.(TBD - Need a way to treat ROUTER boards.)
39 *
40 * There are 2 different structures to represent these boards -
41 * lboard - Local board, rboard - remote board. These 2 structures
42 * can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
43 * Figure below). The first byte of the rboard or lboard structure
44 * is used to find out its type - no unions are used.
45 * If it is a lboard, then the config info of this board will be found
46 * on the local node. (LOCAL NODE BASE + offset value gives pointer to
47 * the structure.
48 * If it is a rboard, the local structure contains the node number
49 * and the offset of the beginning of the LINKED LIST on the remote node.
50 * The details of the hardware on a remote node can be built locally,
51 * if required, by reading the LINKED LIST on the remote node and
52 * ignoring all the rboards on that node.
53 *
54 * The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
55 * First board info on the remote node. The remote node list is
56 * traversed as the local list, using the REMOTE BASE ADDRESS and not
57 * the local base address and ignoring all rboard values.

86 * Each BOARD consists of COMPONENTs and the BOARD structure has
87 * pointers (offsets) to its COMPONENT structure.
88 * The COMPONENT structure has version info, size and speed info, revision,
89 * error info and the NIC info. This structure can accommodate any
90 * BOARD with arbitrary COMPONENT composition.
91 *
92 * The ERRORINFO part of each BOARD has error information
93 * that describes errors about the BOARD itself. It also has flags to
94 * indicate the COMPONENT(s) on the board that have errors. The error
95 * information specific to the COMPONENT is present in the respective
96 * COMPONENT structure.
97 *
98 * The ERRORINFO structure is also treated like a COMPONENT, ie. the
99 * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
100 * structure also has a pointer to the ERRORINFO structure. This is
101 * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
102 * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
103 * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
104 * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
105 * which is present on the REMOTE NODE.(TBD)
106 * REMOTE ERRINFO can be stored on any of the nearest nodes
107 * or on all the nearest nodes.(TBD)
108 * Like BOARD structures, REMOTE ERRINFO structures can be built locally
109 * using the rboard errinfo pointer.
110 *
111 * In order to get useful information from this Data organization, a set of
112 * interface routines are provided (TBD). The important thing to remember while
113 * manipulating the structures, is that, the NODE number information should
114 * be used. If the NODE is non-zero (remote) then each offset should
115 * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
116 * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
117 *
118 * Note that these structures do not provide much info about connectivity.
119 * That info will be part of HWGRAPH, which is an extension of the cfg_t
120 * data structure. (ref IP27prom/cfg.h) It has to be extended to include
121 * the IO part of the Network(TBD).
122 *
