[PATCH 00/18] FWU: Migrate FWU metadata to version 2

[Sughosh Ganu]

The following patches migrate the FWU metadata access code to version
2 of the structure. This is based on the structure definition as
defined in the latest rev of the FWU Multi Bank Update specification
[1].

Since the version 1 of the structure has currently been adopted on a
couple of platforms, it was decided to have a clean migration of the
metadata to version 2 only, instead of supporting both the versions of
the structure. Also, based on consultations with the main author of
the specification, it is expected that any further changes in the
structure would be minor tweaks, and not be significant. Hence a
migration to version 2.

Similar migration is also being done in TF-A, including migrating the
ST platform port to support version 2 of the metadata structure [2].

The patches have been tested on STM32MP1 DK2 board and the Synquacer
board from Socionext. This covers testing both the GPT and the MTD
partitioned storage devices for the metadata access.
