How to Get Android BSP Source Code

Hi, All
I need get the android bsp source code, before, I already get the from qualcomm network, but the package only include the binary file and libs, not include the source code about these libs, Are you tell me, how to get the source code about the BSP, thanks

Not all the libraries used in the vendor images have source available. As best as I remember the Qualcomm tarballs contains the binary only libraries together with build scripts that fetch the open source components from the Coda Aurora git servers.
