I have accustom hardware uses IMX6q which has a intel i210 ethernet controller connected to PCIE of IMX6Q , I had configured the PCIE in Kernel and enabled the e1000 driver , I am able to enumerate the controller ping works fine, etc. whereas when I try to configure the controller and PCIE in UBoot, I see PCI driver listing the devices but the ethernet controller is not seen in the "NET:" looks like the e1000 driver is not getting linked to built-in.o Can someone help me with the correct configuration of the uboot for PCIE and e1000. (I am not using driver model, I am configuring my 2017 in the legacy way.
