I am now working on board bring-up in one of our boards. We have Ethernet interfaces that (probably) won't be used by U-boot at all so I skipped configuring them in U-boot and got them working in the kernel by modifying and adding the appropriate nodes to the DTB.
I am having hard time deciding whether to leave the Ethernet interfaces not configured in U-boot and focus in the kernel. What is the common practice in this situation?
BTW, To get the Ethernet interfaces to work in the kernel, I commented out the Ethernet specific modification to the FDT by U-boot before passing it to the kernel.
