hujun5 f59510ec62 armv[7/8]-r: add ARM_BUSY_WAIT
On a system with multiple CPU cores, when the system is powered on,
multiple cores may start running simultaneously. In this case, software
is required to handle the startup logic for multi-core synchronization.
One approach is to use global variables.
however, the global variable region may not have been initialized yet.
In such scenarios, we can use a busywait flag to
implement the synchronization strategy.
