By default, virtual timers are used. These timers need an offset that must be set by firmware, for example. In case of SMP support, after a reset, this offset is in "unknown" state and produced a hang of the kernel. Use "arm,cpu-registers-not-fw-configured" property allows to use physical timers instead of virtual ones.
