[U-Boot] [PATCH v2 5/7] ARM: add SMP support for non-secure switch

2013-06-13 Thread Andre Przywara
Currently the non-secure switch is only done for the boot processor. To enable full SMP support, we have to switch all secondary cores into non-secure state also. So we add an entry point for secondary CPUs coming out of low-power state and make sure we put them into WFI again after having switche
