It was never set:

In the stmmac_mdio if this is not passed as parameter the bus should
be scanned and the first IDs found should select the right address.
I suppose in your box there is a real transceiver, so maybe the patch
from Gabriel is not actually necessary.
On the GeekBox module there's an RTL8211E phy.
Indeed, reverting Gabriel's commit fixes the observed error messages:
rk_gmac-dwmac ff290000.ethernet eth0: Link is Up - 1Gbps/Full - flow
control rx/tx
so this means that the phy is found and the link auto-negotiated.
Gabriel, it sounds that the patch solved a regression you found on
a configuration where the MAC dialogs with a switch but it breaks the
setup with use a std transceiver.

However, I am unable to ping any hosts on the network now.
hmm, this could be another problem. I wonder if you can
check which recent patch is introducing the problem on ARM64.
For example if this depends on Oct_2015 update.
If you share some logs to me I can take a look at them.
Then we can try to check if the problem in on rx or tx path.
I also ask you yo check the axi settings.
Let me know

eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)
Still with us in next-20160307. CC'ing stmmac maintainers.

do you remember from what revision you rebased away from, when it was
still
working (as a known-good state)?
Hm, next-20160111 possibly... leaving all the 5 days and 4 days ago
changes as candidates ("stmmac: share reset function between dwmac100
and dwmac1000" .. "stmmac: Fix 'eth0: No PHY found' regression").
