* Primary Partition IVFC Hash Tree
* DATA Partition (If applicable)
Only one Partition is active at a given time, this is determined by the DIFF header. Normally the 'data' contained in extdata is stored at level4 of the IVFC hash tree, and hence there are two versions of the 'data' stored in the Extdata image (although only one is 'active'). However if DIFI flags[0] is set, this indicates it is a DATA partition and the 'data' is stored outside the IVFC hash tree, at a relative offset defined by the DIFI partition (in this case there will be only one version of the 'data' stored in the Extdata image).
