OF_LIST can't remain empty that's why setup it up to default DTB.
If it is empty u-boot.img is created without FDT partition: For example: ./tools/mkimage -f auto -A arm -T firmware -C none -O u-boot -a 0x8000000 -e 0 -n "U-Boot 2016.05-rc3 ..." -E -b -d u-boot-nodtb.bin u-boot.img Can't set 'timestamp' property for '' node (FDT_ERR_NOSPACE) FIT description: Firmware image with one or more FDT blobs Created: Wed May 4 15:02:52 2016 Image 0 (firmware@1) Description: U-Boot 2016.05-rc3-00080-gff2e12ae22a8-dirty for zynqmp board Created: Wed May 4 15:02:52 2016 Type: Firmware Compression: uncompressed Data Size: unavailable Architecture: ARM Load Address: 0x08000000 Default Configuration: 'conf@1' Configuration 0 (conf@1) Description: unavailable Kernel: unavailable
And then image like this doesn't contain description and link to FDT and can't boot.
