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