CONFIG_PHY_ROCKCHIP_NANENG_COMBOPHY=y is technically not necessary since it's required only for the M.2 E-KEY slot on the main PCB, but that is used typically for WiFi+BT modules, or on the mezzanine connector but the features exposed behind that connector aren't supported in U-Boot (no DT for it right now). However, if the PHY driver is missing, we get the following error message: pcie_dw_rockchip pcie@fe170000: failed to get pcie phy (ret=-19) and you would need to know which PCIe controller that is before deciding to ignore it. While after enabling the PHY driver, we are greeted with: pcie_dw_rockchip pcie@fe170000: PCIe-2 Link Fail which is a bit more acceptable (to me). The other option would be to disable the PCIe2 PHYs/controllers in the DT, which I'm not too fond of.
