+D-Link DIR-320
+==============
+
+The D-Link DIR-320 wireless router has
+
+  * BCM5354 SoC;
+  * 32 MiB SDRAM;
+  * 4 MiB NOR type Flash Memory;
+  * RS232 serial interface (LV-TTL levels on board!);
+  * 1xUSB interface;
+  * 4 + 1 ethernet interfaces;
+  * 802.11b/g (WiFi) interface;
+  * JTAG interface;
+  * 5 LEDs;
+  * 2 buttons.
+
+The router uses CFE as firmware.
+
+Running barebox
+---------------
+
+Barebox can be started from CFE using tftp.
+You must setup tftp-server on host 192.168.0.1.
+Put your barebox.bin to tftp-server directory
+(usual /tftpboot or /srv/tftp).
+Connect your DIR-320 to your tftp-server network via
+one of four <LAN> sockets.
+
+Next, setup network on DIR-320 and run barebox.bin, e.g.::
+
+  CFE> ifconfig eth0 -addr=192.168.0.99
+  CFE> boot -tftp -addr=a0800000 -raw 192.168.0.1:barebox.bin

+Ritmix RZX-50
+=============
+
+Ritmix RZX-50 is a portable game console for the Russian market.
+
+The portable game console has
+
+  * Ingenic JZ4755 SoC;
+  * 64 MiB SDRAM;
+  * 4 GiB microSDHC card / 4 GiB NAND type Flash Memory (internal boot device);
+  * RS232 serial interface (LV-TTL levels on the board!);
+  * LCD display (480x272);
+  * Video out interface;
+  * 1xUSB interface;
+  * buttons.
+
+The game console uses U-Boot 1.1.6 as bootloader.
+
+Running barebox
+---------------
+
+  1. Connect to the game console's UART
+     (see. http://a320.emulate.su/2012/01/19/uart-na-ritmix-rzx-50/);
+
+  2. Unblock U-Boot console
+     (see. http://a320.emulate.su/2012/01/25/rzx-50-dostup-k-konsoli-u-boot/);
+     Please note that U-Boot's Zmodem support does not work;
+
+  3. Boot Ritmix linux and login;
+
+  4. Build barebox and upload ``barebox.bin`` via Zmodem to the board:
+
+.. code-block:: none
+
+    # cd /tmp
+    # rz
+
+..
+
+  5. Write barebox to onboard flash:
+
+.. code-block:: none
+
+    # dd if=barebox.bin of=/dev/mmcblk0 seek=1048576 bs=1 count=262144
+
+..
+
+  6. Reboot RZX-50, next in U-Boot console start barebox:
+
+.. code-block:: none
+
+  CETUS # msc read 0xa0800000 0x100000 0x40000; g a0800000

+TP-LINK MR3020
+==============
+
+The TP-LINK MR3020 wireless router has
+
+  * Atheros ar9331 SoC;
+  * 32 MiB SDRAM;
+  * 4 MiB NOR type SPI Flash Memory;
+  * RS232 serial interface (LV-TTL levels on board!);
+  * 1 USB interface;
+  * 1 Ethernet interfaces;
+  * 802.11b/g/n (WiFi) interface;
+  * LEDs & buttons.
+
+The router uses U-Boot 1.1.4 as firmware.
+
+Running barebox
+---------------
+
+Barebox can be started from U-Boot using tftp.
+But you have to encode barebox image in a very special way.
+
+First obtain ``lzma`` and ``mktplinkfw`` utilities.
+
+The ``lzma`` utility can be obtained in Debian/Ubuntu
+distro by installing lzma package.
+
+The ``mktplinkfw`` utility can be obtained from openwrt, e.g.::
+
+  $ OWRTPREF=https://raw.githubusercontent.com/mirrors/openwrt/master
+  $ curl -OL $OWRTPREF/tools/firmware-utils/src/mktplinkfw.c \
+          -OL $OWRTPREF/tools/firmware-utils/src/md5.c \
+          -OL $OWRTPREF/tools/firmware-utils/src/md5.h
+  $ cc -o mktplinkfw mktplinkfw.c md5.c
+
+To convert your barebox.bin to U-Boot-loadable image (``6F01A8C0.img``)
+use this command sequence::
+
+  $ lzma -c -k barebox.bin > barebox.lzma
+  $ ./FW/mktplinkfw -c -H 0x07200103 -W 1 -N TL-WR720N-v3 \
+      -s -F 4Mlzma -k barebox.lzma -o 6F01A8C0.img
+
+You must setup tftp-server on host 192.168.0.1.
+Put your ``6F01A8C0.img`` to tftp-server directory
+(usual ``/tftpboot`` or ``/srv/tftp``).
+
+Connect your board to your tftp-server network via Ethernet.
+
+Next, setup network on MR3020 and run ``6F01A8C0.img``, e.g.::
+
+  hornet> set ipaddr 192.168.0.2
+  hornet> set serverip 192.168.0.1
+  hornet> tftpboot 0x81000000 6F01A8C0.img
+  hornet> bootm 0x81000000
