I'm seeing the same issue on the SoCFPGA platform:

libphy: PHY stmmac-0:ffffffff not found
eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)

If I just revert:

   "stmmac: Fix 'eth0: No PHY found' regression"

then the issue goes away.

do you have this patch "stmmac: first frame prep at the end of xmit routine"
? Or you just reverted
   "stmmac: Fix 'eth0: No PHY found' regression"

I only reverted "stmmac: Fix 'eth0: No PHY found' regression". I do have the
patch "stmmac: first frame prep at the end of the xmit routine", but I did not
need to revert that patch.

thx for this input.

FYI, I am reworking the code to manage the mdio inside the driver so a
patch will come soon.
