I don't think we can do that. We should describe the hardware, not drivers/arch capabilities. We shouldn't change DTS after adding support for boooting 2nd CPU core.

Adding brcm,bcm4708 to the list of compatibles doesn't imply that there is a 2nd cpu. The semantic is: if (kernel_knows_how_to_handle(asus,rt-n18u)) handle(as=asus,rt-n18u); else if (kernel_knows_how_to_handle(brcm,bcm47081)) handle(as=brcm,bcm47081); else if (kernel_knows_how_to_handle(brcm,bcm4708)) handle(as=brcm,bcm4708); Best regards Uwe

In the SMP code we would check if (num CPUs > 1 ) then boot up other CPUs end; This num CPUs is fetched from the dts file and it would be checked if that number is equal or smaller than some number in some register which should contain the number of CPUs. We still need the stuff in the bcm47081.dtsi file. If you add a dts file for a device with a BCM4709 or some other SoC not being BCM4708, you should use a similar compatible string. Hauke

I didn't notice that in the first place. Now it's clear, thanks!
