I'm currently manually building a Linux image with some specific drivers for a Xilinx Zynqmp device. Aside from the main Linux tree, there are 2 other mirrored Linux repositories, one from Xilinx and another where the driver was developed with.
I noticed some differences within the source files. I know about the "git blame" function and it tells me it is an older Xilinx developed file which was being used for the driver development.
My Question: How do I track down the exact source file where the driver was build on? I would like to know which branch or tag was cloned/merged in order to build the driver. Because logically the driver developers kernel leaps behind the Xilinx dev kernel. How do I do this?
Any other git tips & tricks in this matter are very much welcome.
