Hi Maxime,
I have test it, but I found it does not work. If using
smp_prepare_cpus, the kernenl cannot find the secondary cpus because
that smp_prepare_cpus semms not be excuted before kernel is booting
secondary cpus. So I have to use early_initcall.At least two other platforms (sti and rockchip) do it like that. And an early_initcall is not an option. Thanks!
