https://wiki.codeaurora.org/xwiki/bin/QAEP/release
1.首先下载repo：
a）终端运行git clone git://codeaurora.org/tools/repo.git
b）mkdir ~/bin
c）拷贝repo 到~/bin下面，修改repo权限，chmod a+x ~/bin/repo
d）修改repo
将REPO_URL='git://android.git.kernel.org/tools/repo.git'改成：REPO_URL='git://codeaurora.org/tools/repo.git'
2.高通源码查找
打开https://wiki.codeaurora.org/xwiki/bin/QAEP/release，找到想要下载的代码的 Manifest（比如：LA.UM.8.2.1.r1-04200-sdm660.0.xml）
3.下载高通源码
以sdm660 android 10.0为例：
a）终端运行 ~/bin/repo init -u git://codeaurora.org/platform/manifest.git -b release -m LA.UM.8.2.1.r1-04200-sdm660.0.xml --repo-url=git://codeaurora.org/tools/repo.git --repo-branch=caf-stable
===> 实测如果使用上面的命令一直卡住的话，可以后面repo 的删了，如下：
~/bin/repo init -u git://codeaurora.org/platform/manifest.git -b release -m LA.UM.8.2.1.r1-04200-sdm660.0.xml
b）repo sync
实测结果如下：
sh:~/works/sdm660$ ~/bin/repo init -u git://codeaurora.org/platform/manifest.git -b release -m LA.UM.8.2.1.r1-04200-sdm660.0.xml
