"RK3066 CPU1 fails to come online with recent kernels....[rest]" or so and also please use the line length up a resonable length like around 70 to 75 characters. Also, is it known, why that happens - i.e. what changed? > Signed-off-by: H=C3=BCseyin BIYIK > Signed-off-by: Johan Jonker > --- > arch/arm/mach-rockchip/platsmp.c | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) >=20 > diff --git a/arch/arm/mach-rockchip/platsmp.c b/arch/arm/mach-rockchip/pl= atsmp.c > index f659d894bfae..d7d080c29f3c 100644 > --- a/arch/arm/mach-rockchip/platsmp.c > +++ b/arch/arm/mach-rockchip/platsmp.c > @@ -133,7 +133,8 @@ static int rockchip_boot_secondary(unsigned int cpu, = struct task_struct *idle) > if (ret < 0) > return ret; > =20 > - if (read_cpuid_part() !=3D ARM_CPU_PART_CORTEX_A9) { > + if (read_cpuid_part() !=3D ARM_CPU_PART_CORTEX_A9 || > + of_machine_is_compatible("rockchip,rk3066a")) { > /* > * We communicate with the bootrom to active the cpus other > * than cpu0, after a blob of initialize code, they will isn't now the only user of the old system the RK3188? With both rk3066 and rk3188 from a similar time, I'd assume both could be switch and thus the the now unused code removed? I've never thought to look into that ... need to find my RK3188 board :-) Heiko
