+Udoo MX6Q/DL board
+
+For information about MX6 Udoo boards:
+http://www.udoo.org/
+
+To build a minimal support for these boards:
+
+    $ make mx6udoo_defconfig
+    $ make
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a micro SD card:

+dd if=output/images/sdcard.img of=/dev/<your-microsd-device>
+
+For details about the medium image layout, see the definition in
