+	# ... or we try to make the "multi" image approach to work

+	#
+	# Sadly, the "multi" image has to consists of three
+	# "fixed" parts in the following "fixed" order:
+	# 1. The kernel which is in $@
+	# 2. The (fake) initrd which is in $@.fakerd
+	# 3. The device tree binary which is in $@.dtb
+	#
+	# Now, given that we use the function for the kernel which
+	# already has a initramfs image inside, we still have to
+	# add a "fake" initrd (which a mkimage header) in the second
+	# part of the legacy multi image. Since we need to put the
+	# device tree stuff into part 3.
