33 /* These structures define the layouts for the TLV items stored in static and
34  * dynamic configuration partitions in NVRAM for EF10 (Huntington etc.).
35  *
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
39  * Siena.
40  *
41  * These are used directly by the MC and should also be usable directly on host
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.)
44  *
45  *                                    -----
46  *
47  * Please refer to SF-108797-SW for a general overview of the TLV partition
48  * format.
49  *
50  *                                    -----
51  *
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,
54  * where:
55  *
56  *   -  L is a location, indicating where this tag is expected to be found:
57  *        0: static configuration
58  *        1: dynamic configuration
59  *        2: firmware internal use
60  *        3: license partition
61  *
62  *   -  TTT is a type, which is just a unique value.  The same type value
63  *      might appear in both locations, indicating a relationship between
64  *      the items (e.g. static and dynamic VPD below).
65  *
66  *   -  NNNN is an index of some form.  Some item types are per-port, some
67  *      are per-PF, some are per-partition-type.
68  *
69  *                                    -----
70  *
71  * As with the previous Siena structures, each structure here is laid out
72  * carefully: values are aligned to their natural boundary, with explicit
73  * padding fields added where necessary.  (No, technically this does not
74  * absolutely guarantee portability.  But, in practice, compilers are generally
75  * sensible enough not to introduce completely pointless padding, and it works
76  * well enough.)
