| * 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. | |
