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