The issue log on core1 is:
root@mpc8572ds:~# ifconfig eth0 10.192.208.244
net eth0: could not attach to PHY
SIOCSIFFLAGS: No such device

To attach PHY node mdio@24520 should not be disabled in dts of core1.
Because all PHYs are controlled through this node as follows:

So you grant it to both partitions?  How do you deal with synchronization?

PHY nodes are only used by ethernet. Each ethernet is used by only one partition
(disabled in the other partition). So I think there is no synchronization issue.

I mean for accessing the MDIO bus.
