Not that Klaus will care for his purposes, but . . .

FYI: the value listed after "Using DTB provided by EFI at "
is what tells me where to reference to print the live DTB
content that is handed over to the FreeBSD kernel via U-boot.

Historically a warm reboot (no power loss) preserved the
content. So I could get back to:

Hit any key to stop autoboot: 

and have it stop and then could then print the DTB content
and capture it. For the above, that would be:

U-Boot> fdt addr 0x3e6cf000
U-Boot> fdt print
