I'll make sure I test your specific patch when you post it, but I can  
already confirm that u-boot.git master happily boots a Khadas Edge board.

I just added the unmodified Edge device tree from mainline Linux into  
arch/arm/dts/, created the u-boot fixup .dtsi and defconfig with

   sed 's/rock-pi-4/khadas-edge/g' configs/rock-pi-4-rk3399_defconfig \
     >configs/khadas-edge-rk3399_defconfig
   cp arch/arm/dts/rk3399-{rock-pi-4,khadas-edge}-u-boot.dtsi
   make khadas-edge-rk3399_defconfig

then built u-boot with an rk3399 bl31.elf from master of  
arm-trusted-firmware.git.

It boots TPL -> SPL -> U-Boot proper -> Linux just fine without any  
external idbloader.bin or standalone trusted firmware - faster and much  
less noisy!

Best wishes,

Chris.
