$PROJECT(s) that support multiple
make imagewill iterate through all board/u-boot configurations defined in
scripts/uboot_helperresulting in ~3-10 images in the target folder. To avoid this behaviour and build a single board-specific image
UBOOT_SYSTEM=<board>can be appended to the build command, e.g. to build an Amlogic image for a LibreComputer LePotato board:
UBOOT_SYSTEM=boxconfiguration which excludes u-boot and provides all device-trees, allowing the image to boot using the Android/BSP u-boot on emmc/spi.
