+OKUD MAX9331
+==============
+
+The USELESS Board seems useless
+
+ * Atheros ar9331 SoC(MIPS24Kc, 400MHz, 32bit);
+ * 64 MiB SDRAM;
+ * 16 MiB NOR type SPI Flash Memory;
+ * 3.3V TTL UART;
+ * 4 GiB USB Nand Flash Disk;
+ * 3 RJ45 Ports;
+ * IEEE 802.11b/g;
+ * 3 User LEDs;
+ * 1 GPIO Button;
+
+The useless board always shiped with the lastest barebox and kernel. OpenWRT
+is supported too.
+
+Perparing Hardware
+------------------
+
+solder the board in the back, use a TTL dongle connect to JP1.
+
+::

+
+
+Running barebox
+---------------
+
+Barebox can be program to the board with:
+
+ * run by u-boot from tftp server
+ * run barebox from RAM or burn to flash by barebox
+ * run from spi flash
+
+Barebox can be started from U-Boot using tftp.
+To convert barebox.bin to u-boot uImage format:
+
+.. code-block:: sh
+
+ $ mkimage -A mips -O linux -T kernel -C none -a a0060000 -e a0060000 -n 'Barebox uImage' -d images/barebox-okud-max9331.img uImage
+ $ cp uImage /var/lib/tftpboot
+
+connect your board to your tftp-server network via Ethernet.
+next, setup network on MAX9331 and run:
+
+.. code-block:: console
+
+ hornet> set ipaddr 192.168.31.17
+ hornet> set serverip 192.168.31.40
+ hornet> tftpboot 0x81000000 uImage
+
+run from ram:
+
+.. code-block:: console
+
+ hornet> bootm 0x81000000
+
+or burn to flash, replace the 0x40000 to your uImage real size,
+
+.. code-block:: console
+
+ hornet> erase 0x9f020000 +0x40000
+ hornet> cp.b 0x81000000 0x9f020000 0x40000
+ hornet> reset
+
+if your board preinstalled with barebox:
+
+run barebox from ram by barebox
+
+copy the image to tftp server folder
+
+.. code-block:: sh
+
+ $ cp images/barebox-okud-max9331.img /var/lib/tftpboot/none-barebox-max9331
+
+enable dhcp service on the network
+
+.. code-block:: console
+
+ global net.server=10.1.1.72
+ boot bnet
+
+if you want to make it valid next boot
+
+.. code-block:: console
+
+ nv net.server=10.1.1.72
+ boot bnet
+
+update barebox by barebox
+
+.. code-block:: console
+
+ barebox_update /mnt/tftp/none-barebox-max9331
+
+run from spi flash
+
+max9331 has 16MiB spi flash on board, layout is like this
+
+.. code-block:: text
+
+ | boot0 | ... | barebox | ... | art |
+
+by default, the barebox bootloader is not located in the begginning of flash,
+instead we have a so called program boot0, it is a very simple program,
+it jump to 0x9f020000 where the first instruction of barebox.
+This is usefull when debug with jtag or choosing different bootloaders.
+or even boot kernel without bootloader.
