2015-10-28	ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_smp()	Vineet Gupta	1	-3/+0
	MCIP now registers it's own per cpu setup routine (for IPI IRQ request) using smp_ops.init_irq_cpu(). So no need for platforms to do that. This now completely decouples platforms from MCIP. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2015-10-28	ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_early_smp()	Vineet Gupta	1	-5/+0
	MCIP now registers it's own probe callback with smp_ops.init_early_smp() which is called by ARC common code, so no need for platforms to do that. This decouples the platforms and MCIP and helps confine MCIP details to it's own file. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
