zynq_z_turn_defconfig: broken networking

[Matwey V. Kornilov]

Hello,

I am running u-boot 2020.04-rc4-00100-g74bf17db39 with
zynq_z_turn_defconfig configuration on MYIR Z-Turn board.
And I see the following when I am trying to run `dhcp' command.


ZYNQ GEM: e000b000, phyaddr 0, interface rgmii-id
mdio_register: non unique device name 'eth0'
ZYNQ GEM: e000b000, phyaddr 0, interface rgmii-id
mdio_register: non unique device name 'eth0'
ZYNQ GEM: e000b000, phyaddr 0, interface rgmii-id
mdio_register: non unique device name 'eth0'
ZYNQ GEM: e000b000, phyaddr 0, interface rgmii-id
mdio_register: non unique device name 'eth0'
No ethernet found.
