+Minimal board support for the Wandboard
+Wandboard's homepage is here:
+This config is only tested with the dual core wandboard.
+You need a micro SD card and a slot/adapter for your development machine.
+Partition the SD card leaving at least 1 MB in front of the first partition.
+Partition layout (example):
+Disk /dev/sdi: 3965 MB, 3965190144 bytes
+255 heads, 63 sectors/track, 482 cylinders
+Units = cylinders of 16065 * 512 = 8225280 bytes
+Sector size (logical/physical): 512 bytes / 512 bytes
+I/O size (minimum/optimal): 512 bytes / 512 bytes
+Disk identifier: 0x77b47445
+ Device Boot Start End Blocks Id System
+/dev/sdi1 2 482 3863632+ 83 Linux
+Copy u-boot and its environment to the SD card:
+sudo dd if=output/images/u-boot.imx bs=512 seek=2 of=/dev/sd<x>
+sudo dd if=output/images/uboot-env.bin bs=512 seek=768 of=/dev/sd<x>
+Copy the root filesystem:
+sudo dd if=output/images/rootfs.ext2 of=/dev/sd<x>1
+Alternative commands to copy root filesystem:
+sudo mkfs.ext4 /dev/sd<x>1
+sudo mount /dev/sd<x>1 /mnt
+sudo tar xf output/images/rootfs.tar -C /mnt
+sudo umount /mnt
