$PROJECT
(s) that support multiple $DEVICE
types make image
will iterate through all board/u-boot configurations defined in scripts/uboot_helper
resulting 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=box
configuration which excludes u-boot and provides all device-trees, allowing the image to boot using the Android/BSP u-boot on emmc/spi.
