Flashing bootloader.bin and u-boot-dtb.img at below offset trigger the
automatic boot from SD. But ADFU needs to long pressed before connecting
the power.

sudo dd if=bootloader.bin of=/dev/sdX bs=512 seek=4097
sudo dd if=u-boot-dtb.img of=/dev/sdX bs=1024 seek=3072

With this is place, u-boot expects GPT layout by default. I am able to boot
the kernel from FAT/ext by updating the bootcmd/u-boot env accordingly. 

I haven't tried flashing/replacing u-boot in eMMC still.
