Use CONFIG_TIMER_CLK_FREQ to let the non-secure init code initialize the generic timer on all CPU's. This allows to make use of the timer freuquency register also on other CPU than the start CPU which is important for KVM.
[Krummenacher Max] Could you elaborate on the 'other CPUs'? The SMP companions Cortex A7 or the Cortex M4.
This is only for the primary A-Class CPU complex. The generic timer is only available there.
And what exactly is KVM here?
Kernel-based Virtual Machine, the Linux integrated hypervisor. The Cortex-A7 support ARM's virtualization extensions which allow to make use of KVM...
