* 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 |
|
* problems. |
