configs/bananapi_m2_zero: new defconfig

Browse Source 
The Banana Pi M2 Zero [1] is a board from Sinovoip, based on the
Allwinner H2+ SoC.

It is similar to the other Banana Pi M2* boards, from which this
configuration is inspired.

Intro
=====
This default configuration will allow you to start experimenting with the
Buildroot environment for the Bananapi M2 Zero. With the current configuration
it will bring-up the board, and allow access through the serial console.
Bananapi M2 Zero link:
http://www.banana-pi.org/m2z.html
This configuration uses U-Boot mainline and kernel mainline.
How to build
============
$ make bananapi_m2_zero_defconfig
$ make
Note: you will need access to the internet to download the required
sources.
How to write the SD card
========================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
$ sync
Insert the micro SDcard in your Bananapi M2 Zero and power it up. The console
is on the Debug UART on the CON3 header, with serial settings 115200 8N1.
