This patchset adds support for booting the secondary CPU cores (and
taking them offline again) on Amlogic Meson8 and Meson8b SoCs.
It is based on an earlier version from Carlo Caione - this helped me
a lot to get a better understanding of how SMP/CPU hotplug works
(compared to the code found in Amlogic's GPL kernel sources from
year 2015).
