/* 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
*
* - 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.)
