Merge patch series "FWU: Add support for FWU metadata version 2"

Browse Source 
Sughosh Ganu <sughosh.ganu@linaro.org> says:

The following patch series adds support for version 2 of the FWU
metadata. The version 2 metadata structure is defined in the latest
revision of the FWU specification [1].

The earlier versions of these patches were migrating to a version 2
only support in U-Boot, similar to TF-A. However, based on feedback
from ST [2], this series has been updated to support both versions. A
platform would still be needed to enable one of the two versions of
metadata through a config symbol.

TF-A has code which reads the FWU metadata and boots the platform from
the active partition. TF-A has decided to migrate the FWU code to a
version 2 only support. These changes have been merged in upstream
TF-A.

These changes have been tested on the ST DK2 board, which uses the GPT
based partitioning scheme. Both V1 and V2 metadata versions have been
tested on the DK2 board.

These changes need to be tested on platforms with MTD partitioned
storage devices.
