[U-Boot] [PATCH 4/6] ARM: add SMP support for non-secure switch

2013-05-06 Thread Andre Przywara
Currently the non-secure switch is only done for the boot processor. To later allow 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 sw
