Some additional register writes are required when hotplugging CPUs on gs101, without these the system hangs when hotplugging. Specifically a CPU_INFORM register needs to be programmed with a hint value which is used by the EL3 firmware (el3mon) and the pmu-intr-gen registers need to be programmed. With this patch applied, and corresponding DT update CPU hotplug now works as expected. e.g. echo 0 > /sys/devices/system/cpu/cpu6/online echo 1 > /sys/devices/system/cpu/cpu6/online Note: to maintain compatibility with older DTs that didn't specify pmu-intr-gen phandle only a warning is issued if the syscon can't be obtained.
