Quectel-CM Source Code

Hi All,
I’m looking for Source Code of the Quectel-CM to integrate into my yocto project for embedded system.
Unfortunatelly google didn’t help to much. I have found couple of project on the github but those are not official releases from Quectel. Could any body point me to the place where I can find it?
Thank you in advance

quectel-CM is only for Quectel Customers, the lastest source only can be obtained from the local FAEs or the sales.
