# Netgear used an old uboot that doesn't have FIT support.
# So we are stuck with either a full ext2/4 fs in a initrd.
# ... or we try to make the "multi" image approach to work
# for us.
#
# 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.
