Yes, we need both the patch series. The first series([PATCH v8 00/13]
FWU: Add FWU Multi Bank Update feature support) adds support for the
feature and for platforms with GPT partitioning layout, and is
enabling the feature on the ST DK2 board. The second series is adding
support for the feature on MTD partition based devices and enabling
the feature on the Synquacer board.
