iMX6 PCIe for a beginner...

Hello,

 

I need to learn PCIe for the iMX6Q to communicate with an FPGA, EIM is not an option here. I am looking for some help. I know that the Kernel needs to be configured and support needs to be added for the Freescale driver in the Kernel. Where I am having trouble is how do I interact with the Freescale driver; or do I need to write my own? When looking at the pcie-imx6.c file there seems to be a lot of chip specific information as well as the .compatible being setup for the device tree.

When reading articles on Linux PCIe driver development the way a driver a written is different from the pcie-imx6.c file. Is there a simple PCIe example for the iMX6 anywhere?

 

Again, any help is appreciated.
