学习STM32,看了一堆乱七八糟的文档，准备写程序了，先分析了下STM32的启动代码，看着这堆鬼鬼的汇编代码，挺吓人的，看看帮助，查查网路，还是不那么难懂。

StackConfiguration - ;//
StackSize(inBytes)<0x0-0xFFFFFFFF:8> - ;//
- Stack_SizeEQU0x00000200;//定义堆栈大小
- AREASTACK,NOINIT,READWRITE,ALIGN=3;//定义一个数据段按8字节对齐
- Stack_MemSPACEStack_Size;//保留Stack_Size大小的堆栈空间
- __initial_sp;//标号，代表堆栈顶部地址，后面有用
