For the STM32MP15 DHSOM, change the default environment so an AB schema on a device can be detected. For this the define "SCAN_DEV_FOR_BOOT_PARTS" is overwritten and appended. The detection works by looking for the partitions with specific lables. The name of those partitions are in the variables and its defaults: * dh_ab_partname_primary=rootfs-a * dh_ab_partname_secondary=rootfs-b To prevent being hanging at bootcmd, enable "CONFIG_BOOT_RETRY" and "CONFIG_RESET_TO_RETRY", but the timer will only be activated, if the AB partitions are detected.
