从主页找到R40对应开发板，
- Banana Pi BPI-M2 Berry [Allwinner R40/V40/A40i]
- Banana Pi BPI-M2U [Allwinner R40/V40/A40i]
其中Banana Pi BPI-M2U的Wiki介绍了如何编译BSP，其中使用内核也是Tina Linux，
$ cd project/
$ git clone https://github.com/BPI-SINOVOIP/BPI-M2U-bsp.git
$ cd BPI-M2U-bsp/
# pack的时候会要求输入sudo密码
$ ./build.sh BPI-M2B-1080P 1
# 编译完成之后生成
$ ls -l SD/bpi-m2b/

全志
Linux内核，看Wiki，这个应该是不支持R40/A40i/A40Pro（消费级/工业级/军事级）的sun8i，tinalinux/linux-3.10是Wiki上R40 Linux SDK指向的Linux内核，后面的香蕉派，都是使用Tina维护的内核，
内核态驱动，可参考linux-sunxi把驱动放进A40i的内核代码目录，或者在代码树外部直接编译驱动，
用户态库，
Mali-400 X11的DRI2/EXA驱动，xf86-video-mali是官方的，真正使用的应该是xf86-video-fbturbo
Tina Linux
Tina Linux的Wiki，Github，Tina Linux是一整套开发包，从u-boot到linux到rootfs，采用OpenWRT的编译方式，编译安装用repo等命令，这个我以前没用过，
R40/A40i/A40pro/V40
R40介绍，里面有它的软硬件资源链接，
Allwinner R40 (sun8i) SoC features a Quad-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. It is a not-pin-compatible quad core sucessor of the A20. It’s also known as the Allwinner T3 for In-Car Entertainment usage. A40i and A40pro are variants that differ in applicable temperatures range (industrial and military).
全志使用sysconfig.fex文件来配置各种参数，之后编译过程中转换成dts文件。
CPU Architecture
• Quad-core ARM CortexTM-A7 Processor
• ARMv7 ISA standard ARM instruction set
• Thumb-2 Technology
