How did you test them? I am surprised that COMPHY calls worked for you out of the box. I am not sure you have A3700 COMPHY support in your ATF but it probably work because U-Boot is doing the initial configuration. > 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.

The driver already handles these calls (see [1]), making use of them is just a matter of hacking into drivers (in your case, I suppose it is mvneta) and add phy_set_mode()/phy_power_on() calls.
