Enable automatic detection of the active A/B bank by retrieving partition GUIDs from FWU metadata. This ensures the system correctly identifies the bootable partitions even in multi-bank scenarios, falling back to a standard bootable flag scan if the UUIDs are missing. To enable A/B bank bootup on stm32mp25 boards, add the following Kconfig options to the stm32mp25_defconfig: CONFIG_FWU_MULTI_BANK_UPDATE=y CONFIG_FWU_MDATA=y CONFIG_FWU_NUM_BANKS=2 CONFIG_FWU_NUM_IMAGES_PER_BANK=3 CONFIG_CMD_FWU_METADATA=y CONFIG_FWU_MDATA_V2=y Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com>
