Removing this document caused a warning at Documentation/arm/booting.rst:

	$ ./scripts/documentation-file-ref-check 
	Documentation/arm/booting.rst: Documentation/devicetree/booting-without-of.rst

as it mentions that the DTB format is described on booting-without-of.rst:

	4b. Setup the device tree
	-------------------------

	The boot loader must load a device tree image (dtb) into system ram
	at a 64bit aligned address and initialize it with the boot data.  The
	dtb format is documented in Documentation/devicetree/booting-without-of.rst.
	The kernel will look for the dtb magic value of 0xd00dfeed at the dtb
	physical address to determine if a dtb has been passed instead of a
	tagged list.

So, I guess that such part of the document needs to be moved to booting.rst.

Thanks,
Mauro
