| * This file implements the assembly entry point for secondary CPUs in |
| * an SMP kernel. The only thing we need to do is to add the CPU to |
| * the coherency fabric by writing to 2 registers. Currently the base |
| * register addresses are hard coded due to the early initialisation |
| #include <linux/linkage.h> |
| #include <asm/assembler.h> |
| * Armada XP specific entry point for secondary CPUs. |
| * We add the CPU to the coherency fabric and then jump to secondary |
