/* These structures define the layouts for the TLV items stored in static and
 * dynamic configuration partitions in NVRAM for EF10 (Huntington etc.).
 *
 * They contain the same sort of information that was kept in the
 * siena_mc_static_config_hdr_t and siena_mc_dynamic_config_hdr_t structures
 * (defined in <ci/mgmt/mc_flash_layout.h> and <ci/mgmt/mc_dynamic_cfg.h>) for
 * Siena.
 *
 * These are used directly by the MC and should also be usable directly on host
 * systems which are little-endian and do not do strange things with structure
 * padding.  (Big-endian host systems will require some byte-swapping.)
 *
 *                                    -----
 *
 * Please refer to SF-108797-SW for a general overview of the TLV partition
 * format.
 *
 *                                    -----
 *
 * The current tag IDs have a general structure: with the exception of the
 * special values defined in the document, they are of the form 0xLTTTNNNN,
 * where:
 *
 *   -  L is a location, indicating where this tag is expected to be found:
 *        0: static configuration
 *        1: dynamic configuration
 *        2: firmware internal use
 *        3: license partition
 *        4: tsa configuration
 *
 *   -  TTT is a type, which is just a unique value.  The same type value
 *      might appear in both locations, indicating a relationship between
 *      the items (e.g. static and dynamic VPD below).
 *
 *   -  NNNN is an index of some form.  Some item types are per-port, some
 *      are per-PF, some are per-partition-type.
 *
 *                                    -----
 *
 * As with the previous Siena structures, each structure here is laid out
 * carefully: values are aligned to their natural boundary, with explicit
 * padding fields added where necessary.  (No, technically this does not
 * absolutely guarantee portability.  But, in practice, compilers are generally
 * sensible enough not to introduce completely pointless padding, and it works
 * well enough.)
