+A20-OLinuXino-LIME and A20-OLinuXino-MICRO
+
+Intro
+=====
+
+These are open hardware boards, both based an the AllWinners A20 SoC.
+
+for more details about the boards see the following pages:
+ - https://www.olimex.com/Products/OLinuXino/open-source-hardware
+ - https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-MICRO/
+ - https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME/
+
+The following defconfigs are available:
+ - olimex_a20_olinuxino_micro_defconfig
+   for the A20-OLinuXino-MICRO board using mainline kernel
+ - olimex_a20_olinuxino_lime_defconfig
+   for the A20-OLinuXino-LIME board using mainline kernel
+ - olimex_a20_olinuxino_lime_mali_defconfig
+   for the A20-OLinuXino-LIME board using legacy linux-sunxi kernel
+ - olimex_a20_olinuxino_lime2_defconfig
+   for the A20-OLinuXino-LIME2 board using mainline kernel
+
+The legacy linux-sunxi kernels are based on the vendor code drops.
+They are only useful when accelerated 3D graphics and multimedia support
+is strictly necessary.
+
+The Mainline Kernel is already a much better choice for a headless server.
+And also the mainline kernel works fine even for a basic Linux desktop
+system running on top of a simple framebuffer, which may be good enough for
+the users who do not need fancy 3D graphics or video playback acceleration.
+
+(see http://linux-sunxi.org/Linux_Kernel for more details)
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make <board>_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
+    +-- script.bin (lime_mali)
+    +-- sun7i-a20-olinuxino-lime.dtb (lime, mainline)
+    +-- sun7i-a20-olinuxino-lime2.dtb (lime2, mainline)
+    +-- sun7i-a20-olinuxino-micro.dtb (micro, mainline)
+    +-- 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
+

+    /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 board, and power it up.
