Miquel, I tried the patches and they are working, with the exception of Compex WLE900X card, but we know that this card is problematic. I am interesting if there is a known way to turn of the comphy on A3720, or at least change the SGMII mode from 1Gbps to 2.5Gbps and back. Marvell documentation does not provide this information and the code in ATF providing the SMC calls does not do this either. Do you know how this can be achieved?
