33 /* These structures define the layouts for the TLV items stored in static and
34 * dynamic configuration partitions in NVRAM for EF10 (Huntington etc.).
36 * They contain the same sort of information that was kept in the
37 * siena_mc_static_config_hdr_t and siena_mc_dynamic_config_hdr_t structures
38 * (defined in <ci/mgmt/mc_flash_layout.h> and <ci/mgmt/mc_dynamic_cfg.h>) for

42 * systems which are little-endian and do not do strange things with structure
43 * padding. (Big-endian host systems will require some byte-swapping.)
47 * Please refer to SF-108797-SW for a general overview of the TLV partition
52 * The current tag IDs have a general structure: with the exception of the
53 * special values defined in the document, they are of the form 0xLTTTNNNN,
56 * - L is a location, indicating where this tag is expected to be found:
57 * 0 for static configuration, or 1 for dynamic configuration. Other
58 * values are reserved.
60 * - TTT is a type, which is just a unique value. The same type value
61 * might appear in both locations, indicating a relationship between
62 * the items (e.g. static and dynamic VPD below).
64 * - NNNN is an index of some form. Some item types are per-port, some
65 * are per-PF, some are per-partition-type.
69 * As with the previous Siena structures, each structure here is laid out
70 * carefully: values are aligned to their natural boundary, with explicit
71 * padding fields added where necessary. (No, technically this does not
72 * absolutely guarantee portability. But, in practice, compilers are generally
73 * sensible enough not to introduce completely pointless padding, and it works
