* Every level comes in pairs (concatenated), so the actual size of each level is twice as large as recorded in the "size" field. Level n (n = 1 or 2) is a bit-array (encoded in u32 array, with MSB as the first bit of each 32 bits), in which each bit corresponds to a block in level (n+1), indicating in which of the pair the block is the active one (0 means the first one, 1 means the second one). In this way, the actual valid data is scattered between the two IVFC partition images.

* The valid one in level 1 pair is chosen by "DPFS level 1 selector" in DIFI.

* The offsets contained in the DPFS are relative to the partition offset in the DISA/DIFF. The offsets from the IVFC are related to the IVFC partition (DPFS Level 3), after assembling the valid data.
