  31 /* These structures define the layouts for the TLV items stored in static and
  32  * dynamic configuration partitions in NVRAM for EF10 (Huntington etc.).
  33  *
  34  * They contain the same sort of information that was kept in the
  35  * siena_mc_static_config_hdr_t and siena_mc_dynamic_config_hdr_t structures
  36  * (defined in <ci/mgmt/mc_flash_layout.h> and <ci/mgmt/mc_dynamic_cfg.h>) for
  37  * Siena.
  38  *
  39  * These are used directly by the MC and should also be usable directly on host
  40  * systems which are little-endian and do not do strange things with structure
  41  * padding.  (Big-endian host systems will require some byte-swapping.)
  42  *
  43  *                                    -----
  44  *
  45  * Please refer to SF-108797-SW for a general overview of the TLV partition
  46  * format.
  47  *
  48  *                                    -----
  49  *
  50  * The current tag IDs have a general structure: with the exception of the
  51  * special values defined in the document, they are of the form 0xLTTTNNNN,
  52  * where:
  53  *
  54  *   -  L is a location, indicating where this tag is expected to be found:
  55  *        0: static configuration
  56  *        1: dynamic configuration
  57  *        2: firmware internal use
  58  *        3: license partition
  59  *
  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).
  63  *
  64  *   -  NNNN is an index of some form.  Some item types are per-port, some
  65  *      are per-PF, some are per-partition-type.
  66  *
  67  *                                    -----
  68  *
  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
  74  * well enough.)
