If this doesn't help, undo the revert and repartition the SD card such
that the preloader partition is located at 2048 sectors from start (that's
where U-Boot expects it for now, there's space for improvement) and write
the u-boot-with-spl-dtb.sfp to that partition.

$ sudo fdisk  -l /dev/sdg
Disk /dev/sdg: 14.9 GiB, 16003891200 bytes, 31257600 sectors
