+A20-OLinuXino-LIME
+
+Intro
+=====
+
+This is a open hardware board,
+see https://www.olimex.com/Products/OLinuXino/open-source-hardware
+
+How to build it
+===============
+
+ $ make olimex_a20_olinuxino_lime_defconfig
+
+Compile everything and build the rootfs image:
+
+ $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+ output/images/
+ +-- rootfs.ext2
+ +-- rootfs.ext4 -> rootfs.ext2
+ +-- sun7i-a20-olinuxino-lime.dtb
+ +-- u-boot.bin
+ +-- u-boot-sunxi-with-spl.bin
+ `-- zImage
+
+
+How to write the SD card
+========================
+
+
+Prepare the SD card
+-------------------
+
+Erase existing stuff, and create an unique Linux partition with `fdisk`.
+
+ # fdisk /dev/sdX
+ Command (m for help): o
+ Building a new DOS disklabel with disk identifier 0xf9e1616a.
+ Changes will remain in memory only, until you decide to write them.
+ After that, of course, the previous content won't be recoverable.
+
+ Command (m for help): n
+ Partition type:
+ p primary (0 primary, 0 extended, 4 free)
+ e extended
+ Select (default p): p
+ Partition number (1-4, default 1): 1
+ First sector (2048-7626751, default 2048): 2048
+ Last sector, +sectors or +size{K,M,G} (2048-7626751, default 7626751):
+ Using default value 7626751
+
+ Command (m for help): p
+
+ Disk /dev/sdX: 3904 MB, 3904897024 bytes
+ 4 heads, 16 sectors/track, 119168 cylinders, total 7626752 sectors
+ Units = sectors of 1 * 512 = 512 bytes
+ Sector size (logical/physical): 512 bytes / 512 bytes
+ I/O size (minimum/optimal): 512 bytes / 512 bytes
+ Disk identifier: 0xf9e1616a
+
+ Device Boot Start End Blocks Id System
+ /dev/sdX1 2048 7626751 3812352 83 Linux
+
+ Command (m for help): w
+ The partition table has been altered!
+
+ Calling ioctl() to re-read partition table.
+ Syncing disks.
+
+Copy images on the SD card
+--------------------------
+
+ # dd if=output/images/rootfs.ext2 of=/dev/sdX1
+ # dd if=output/images/u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
+
+
+Finish
+======
+
+Eject the SD card, insert it in the A20-OLinuXino-LIME board, and power it up.
