Hi,
It appears that commit e34d65696d2e 'stmmac: create of compatible mdio
bus for
stmmac driver' is causing this error on the SoCFPGA platform:
[ 1.767246] libphy: PHY stmmac-0:ffffffff not found
[ 1.772106] eth0: Could not attach to PHY
[ 1.776129] stmmac_open: Cannot attach to PHY (error: -19)
[ 1.781590] IP-Config: Failed to open eth0
[ 1.785681] IP-Config: No network devices available
Doing a revert of this commit fixes the issue. Will try to debug further.
Thanks,
Dinh
