  47  * On the top level, an MFA2 file contains:
  48  *  - Fingerprint
  49  *  - Several multi_tlvs (TLVs of type MLXFW_MFA2_TLV_MULTI, as defined in
  50  *    mlxfw_mfa2_format.h)
  51  *  - Compresses content block
  52  *
  53  * The first multi_tlv
  54  * -------------------
  55  * The first multi TLV is treated as package descriptor, and expected to have a
  56  * first TLV child of type MLXFW_MFA2_TLV_PACKAGE_DESCRIPTOR which contains all
  57  * the global information needed to parse the file. Among others, it contains
  58  * the number of device descriptors and component descriptor following this
  59  * multi TLV.
  60  *
  61  * The device descriptor multi_tlv
  62  * -------------------------------
  63  * The multi TLVs following the package descriptor are treated as device
  64  * descriptor, and are expected to have the following children:
  65  *  - PSID TLV child of type MLXFW_MFA2_TLV_PSID containing that device PSID.
  66  *  - Component index of type MLXFW_MFA2_TLV_COMPONENT_PTR that contains that
  67  *    device component index.
  68  *
  69  * The component descriptor multi_tlv
  70  * ----------------------------------
  71  * The multi TLVs following the device descriptor multi TLVs are treated as
  72  * component descriptor, and are expected to have a first child of type
  73  * MLXFW_MFA2_TLV_COMPONENT_DESCRIPTOR that contains mostly the component index,
  74  * needed for the flash process and the offset to the binary within the
  75  * component block.
