Instead of a command I would prefer if you could just store r2 from
the original bootloader you have been started with, and in a board
specific initcall you copy the devicetree you found in memory to a
file. Then the user has access to the devicetree with regular file
commands and there is no need to guess the memory address where the
original bootloader stored the device tree.
