boards: add FriendlyARM Nanopi NEO
The FriendlyARM Nanopi NEO is a 4x4cm² board with an Allwiner H3 SoC: - quad-core Cortex-A7 @1.2GHz - 256 or 512MiB of DDR - uSDCard as only storage option - 3x USB 2.0 host (one socket, two on expansion pin-holes) - 1x USB 2.0 OTG (also used as power source) - 10/100 etehrnet MAC - GPIOs, SPI, I2c... Support for the Nanopi NEO in U-Boot and Linux is very recent, so much so that we have to use an -rc tag for U-Boot and a special Linux tree. As for Linux, I pushed a git tree on Github with a single tag that matches what is currently queued in the sunxi-next queued for 4.10, based on 4.9-rc3. All those commits are from Maxime's tree, the maintainer for most sunxi stuff. This also means that we can't use the Linux headers from the kernel being built (which is what we usually do) because those report 4.9, while Buildroot currently knows only of 4.8 at best. So this is what we use. Unfortunately, support for the ethernet MAC and the USB OTG are not yet upstream, but are being actively worked on. The Nanopi NEO is very similar to the Orangepi PC, so I was able to scanvenge most of its configuration. ;-) Thanks Maxime for your help on IRC! :-) Signed-off-by: "Yann E.

+Intro
+=====
+
+The instructions herein are valid for the FriendlyARM NanoPi NEO,
+both the 256MiB and 512MiB versions. They should also work the the
+NanoPi NEO Air, but this is untested so far.
+
+The FriendlyARM Nanopi NEO is a 4x4cm² board with an Allwiner H3 SoC:
+ - quad-core Cortex-A7 @1.2GHz
+ - 256 or 512MiB of DDR
+ - uSDCard as only storage option
+ - 3x USB 2.0 host (one socket, two on expansion pin-holes)
+ - 1x USB 2.0 OTG (also used as power source)
+ - 10/100 ethernet MAC
+ - GPIOs, SPI, I2c...
+
+Support for the Nanopi NEO in U-Boot and Linux is very recent, so
+much so that we have to use an -rc tag for U-Boot and a special
+Linux tree.
+
+Unfortunately, support for the ethernet MAC and the USB OTG are not
+yet upstream, but are being actively worked on.
+
+
+How to build
+============
+
+ $ make nanopi_neo_defconfig
+ $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+You will then obtain an image ready to be written to your micro SDcard:
+
+ $ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+
+Notes:
+ - replace 'sdX' with the actual device with your micro SDcard,
+ - you may need to be root to do that (use 'sudo').
+
+Insert the micro SDcard in your NanoPi NEO and power it up. The console
+is on the serial line, 115200 8N1.
