Question regarding A15 L2ACTLR register programming (auto clock gating)

Hi,

This question is regarding Cortex-A15 L2ACTLR[27] bit ("Force L2 logic clock enable active"). If the clock to L2 block has to be forced to be active all the time (L2ACTLR[27] = 1), is it sufficient if one of the A15 Cores in the MPCore setting this bit? Or does all the four CPUs in the A15 MPcore need to set this bit?

Thanks,

Thomas.
