Attached is the boot log where reboot works as expected with all A15 core up. Although I have tested the internal release based on 3.10 where all the cores are up which used bootarg apmu=multicluster (https://patchwork.kernel.org/patch/3948791/). So there is some work involved to get all the A7's up and running.
