	TC654    (i2c-0 @ 0x1b - Dual PWM fan Speed controller)

WARNING: The serial port needs a TTL/RS-232 v3.3 level converter!

INFO: Since this device only has a NAND chip. I opted for going with
root.squashfs in a UBI volume. There's no squashfs/jffs2 image.

This target produces three images.
  a. netgear factory image
     This image can be used to flash the Netgear WNDR4700 via the
     firmware recovery mechanism and the web admin site.

     The bootloader can be instructed to do a firmware recovery via the
     # fw_recovery
     command. It will start a tftp server and listen on 192.168.1.1
     (the ipaddr variable in u-boot) for incoming, binary tftp clients.
     The firmware recovery mechanism is also started if any of the flash
     content which contains the kernel, device-tree definitions or the
     (fake)rootfs fails to verify or load.

  b. sysupgrade.tar image for sysupgrade
     An sysupgrade will replace the entire current LEDE installation
     with a newer version. This does include the kernel and the ubi rootfs
     partition. The configuration can be carried over automatically as well
     if desired.

     simply copy the sysupgrade.tar to a the WNDR4700 running LEDE and run:

     root@lede:~# sysupgrade sysupgrade.tar

     and let it reboot.

     Note: The devicetree flash area is NOT updated. Until the devicetree
	   definition is stable, this can lead to all sorts of hardware
	   detection problems! So make sure, if you experience issues: try
	   the fw_recovery. If you are unsure whenever this affects you:
	   test if you can reproduce your issue with the initramfs method.
	   As it will always have up-to-date device-tree definitions.

  c. initramfs image for TFTP (for development and testing)
     To use the initramfs method, follow the following steps:
       1) Move the "lede-apm821xx-netgear-WNDR4700-initramfs-kernel.bin"
	  file to to the root directory of your TFTP server.

       2) rename it to wndr4700.bin

       3) On the WNDR4700 - Hit Enter during u-boot and insert:
	  # tftp 400000 wndr4700.bin; run addtty; bootm 400000 -

     This will boot the LEDE image.

     Note: The default tftp server is 192.168.1.7, if you want to change it:
     # setenv serverip 192.168.8.7;

     Note2: The default address for the WNDR4700 is 192.168.1.1:
     # setenv ipaddr 192.168.8.8;

     Note: Connect you tftp server on the last LAN port (not the WAN)

Note: The firmware for the USB 3.0 Host chip is not included anymore.
Therefore the two USB 3.0 ports will not work without the
uPD7070x-firmware package installed.

# 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.
