Technically, yes. In practice, MDIO and MAC drivers are probed separately. I don't see any better solution, should I just leave the core1's mdio node intact? > And are we just ignoring the possibility of races between multiple > partitions accessing the shared mdio block? Dunno. From simply looking into the device tree, I'd assume the same.
