Armada 3720 alike Board - no PHY devices found by mii info, no ping

[Lev Olshvang]

Hello list,

I work with a variant of Marvell Armada 3720 board.
Recently I upgrade Uboot version from 2017 to 2023.07.
As a result PING command failed
Original version of 2017 reports on mii info command
PCPE>> mii info
    PHY 0x01: OUI = 0x5A985, Model = 0x2A, Rev = 0x06, 100baseT, HDX
Whilst my new 2023 can not find PHY devices

I made minimal changes to configuration  and Device tree files.
Compilation passed, I loaded Uboot using Uart and it successfully reached PCPE prompt
So I tried to test network .
Ping correctly reports it uses  eth1 at neta40000 as output interface (exactly as  v2017 does),
but ping failed
 
I did not touch at all PHY and ethernet related definitions, leaving them exactly as it was.

Please advise what to look for.

I do not know how to send full DTS file to list, please instruct me.
Meanwhile I do copy-paste.
