【求助】ARM Cortex A9 双核例程

有没有前辈用过ARM双核？CPU0怎么唤醒CPU1？看了zynq的手册，描述如下：
The steps for CPU 0 to start an application on CPU 1 are as follows:
1. Write the address of the application for CPU 1 to 0xFFFFFFF0.
2. Execute the SEV instruction to cause CPU 1 to wake up and jump to the application.

意思懂了，代码不会写。怎么把代码放在0xFFFFFFF0处？
