mvebu: uDPU: switch default kernel and U-Boot PHY mode Certain SFP modules (most notably Nokia GPON ones) first check connectivity on 1000base-x, and switch to 2500base-x afterwards. This is considered a quirk so the phylink switches the interface to 2500base-x as well. However, after power-cycling the uDPU device, network interface/SFP module will not work correctly until the module is re-seated. This patch resolves this issue by forcing the interface to be brought up in 2500base-x mode by default.
