下载HI3516DV300官方板子的固件，烧写到自己的板子上，虽然不能正常使用，但主要看一些信息。

”双核 SMP“ 之前已经知道了，”使用GICv2“也可以搜索到
”releasing 1 secondary cores“之后先是”cpu 0 entering scheduler“
在

LosProcessCB *runProcess = NULL;
LosTaskCB *taskCB = NULL;
UINT32 cpuid = ArchCurrCpuid();
OsTickStart();

runProcess = OS_PCB_FROM_PID(taskCB->processID);
runProcess->processStatus |= OS_PROCESS_STATUS_RUNNING;

#endif

OsStart();
while (1) {
__asm volatile(“wfi”);
}
}
而在release_secondary_cores()使用了WFE等待，说明正常情况下WFE被唤醒，唤醒后，CPU0先调度，再是CPU1调度。
这个前面应该是有唤醒，只是自己没注意。所以我之前的想法是错误的。
只要启动调度了，那么剩下的系统启动过程，也都差不多一样的了。
