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
18 * problems.
