ubuntu 14.04
内核版本4.4.0-31，闲话两句
不知道是不是因为墙的问题，尝试了不同的ubuntu16/18版本+optee版本，最后使用ubuntu14+optee3.1才第一次跑通，各种缺文件，自行测试最新版吧

# 修改源 可选
$ vim /etc/apt/sources.list

配置

# 安装repo
$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ cd ~/bin
$ curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo
$ chmod a+x repo
$ git config --global user.name "yourname"
$ git config --global user.email "youremail"

Sync and make

$ mkdir -p $HOME/devel/optee
$ cd $HOME/devel/optee
$ repo init -u https://github.com/OP-TEE/manifest.git -m rpi3.xml -b 3.1.0 
# --repo-url=https://mirrors.tuna.tsinghua.edu.cn/git/git-repo
# 可选，init失败时加到3.1.0 后面
$ repo sync

$ cd build
$ make toolchains

$ make

可选：下载toolchains失败时

$ gedit /optee/build/toolchain.mk
# 粗看一下很好理解，组合成下载URL手动下载，然后解压
# https://releases.linaro.org/components/toolchain/binaries/6.2-2016.11/arm-linux-gnueabihf/${AARCH32_GCC_VERSION}.tar.xz
# gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf替代${AARCH32_GCC_VERSION}就是文件路径
$ mkdir -p aarch32 && mkdir -p xxx && mkdir -p xxx ... # AARCH32_PATH中的文件夹名称
$ tar xf xxx.tar.xz -C aarch32xxx --strip-components=1; &&  tar xf ...
