Thanks ! After ATF update to 18.12 both USB and PCIe are working fine
without any changes to DTS. But network interfaces including 1G copper
interface still do not work as expected:

$ ip link set eth0 up                                                                                                                                                                             
[  626.774003] mvpp2 f2000000.ethernet eth0: could not attach PHY (-19) RTNETLINK answers: No such device
$ ip link set eth2 up
[  504.054084] mvpp2 f4000000.ethernet eth2: could not attach PHY (-19) RTNETLINK answers: No such device

I have not changed configuration since 5.3, so all the marvell phy
drivers are in place. Is there anything in configuration that could
be missed after moving from 5.3 to 5.6 kernel ?

Sergey
