Added a default configuration file and supporting board support files
for the Banana Pi M2 Ultra platform. The port is based on the ports for
the Banana Pi M1 and Banana Pi M2 Plus platforms, and provides for a
duplicate feature set. In addition to the default configuration file this
port includes a boot script, an SD card definition file and a readme file
explaining its usage.

+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Bananapi M2U. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+Bananapi M2U link:
+http://www.banana-pi.org/m2u.html
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+How to build
+============
+
+    $ make bananapi_m2_ultra_defconfig
+    $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+  $ sudo sync
+
+Insert the micro SDcard in your Bananapi M2U and power it up. The console
+is on the serial line, 115200 8N1.
