+ * Each BOARD consists of COMPONENTs and the BOARD structure has

+ * 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).

+ * Description: This register's value is a bit vector that guards *

+ * LB_REV_ID register, which is documented in Section 8.3.1.1). The *
+ * protection provided by this register applies to PIO read *
+ * operations as well as PIO write operations. The II will perform a *
+ * PIO read or write request only if the bit for the requestor's *
+ * region is set; otherwise, the II will not perform the requested *
+ * operation and will return an error response. When a PIO read or *
+ * write request targets an external Crosstalk widget, then not only *

+ * also the target widget's bit in the IOWA register must be set in *
+ * order for the II to perform the requested operation; otherwise, *
+ * the II will return an error response. Hence, the protection *
+ * provided by the IOWA register supplements the protection provided *

+ * cpu_logical_id(phy_id) - convert a <physical_cpuid> to a <cpuid>
+ * * not real efficient - don't use in perf critical code
+ *
+ * SLICE - a number in the range of 0 - 3 (typically) that represents the
+ * cpu number on a brick.
+ *
+ * SUBNODE - (almost obsolete) the number of the FSB that a cpu is
+ * connected to. This is also the same as the PI number. Usually 0 or 1.

+ * NOTE!!!: the value of the bits in the cpu physical id (SAPICid or LID) of a cpu has no
