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:
mdio@24520 {
phy0: ethernet-phy@0 {
interrupts = <10 1 0 0>;
reg = <0x0>;
};
phy1: ethernet-phy@1 {
interrupts = <10 1 0 0>;
reg = <0x1>;
};
phy2: ethernet-phy@2 {
interrupts = <10 1 0 0>;
reg = <0x2>;
};
phy3: ethernet-phy@3 {
interrupts = <10 1 0 0>;
reg = <0x3>;
};
tbi0: tbi-phy@11 {
reg = <0x11>;
device_type = "tbi-phy";
};
};

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