I would think that using the 'fdt' command in U-Boot to add all
properties of every cape found on a running system would drive someone
to madness quite quickly. Moving all of Pantelis' work for dynamic
device trees from the kernel to N bootloaders (U-Boot, barebox, UEFI,
etc) sounds like a step in the wrong direction.
