[Buildroot] [PATCH 1/1] New board: FriendlyARM NanoPi Duo

[Sven Haardiek]

Introduce a new board the FriendlyARM NanoPi Duo.

- Due to the missing defconfigs and DTS in the mainline kernel and uboot, I
  used the ones from the FriendlyARM github page.

- Most of the configuration was copied from the other friendlyarm boards.

+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Nanopi DUO. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+Nanopi DUO link:
+http://www.nanopi.org/Nanopi-Duo_Feature.html
+
+Wiki link:
+http://wiki.friendlyarm.com/wiki/index.php/NanoPi_Duo
+
+How to build
+============
+
+    $ make friendlyarm_nanopi_duo_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 Nanopi DUO and power it up. The console is on
+the serial line, 115200 8N1.
