1.0.2的stm32f20x编译问题

初用RTT，官方的BSP的编译都没有通过，不好意思上来问问。

环境：RT-Thread 1.0.2.7z，Keil，scons，和Arda Scnons GUI。编译路径：bsp stm32f20x

rtconfig.h 未改动前，用Arda Scons编译，有个警告：
```> armcc -o buildspstartup.o
> "startup.c", line 108: Warning:  #223-D: function "rt_hw_rtc_init" declared implicitly
>   	rt_hw_rtc_init();
>   	^
> startup.c: 1 warning, 0 errors
> armcc -o buildspstm32f20x_it.o```

用Keil编译project.uvproj

```compiling startup.c...
startup.c(108): warning:  #223-D: function "rt_hw_rtc_init" declared implicitly
compiling sdio_sd.c...
sdio_sd.c(1320): warning:  #223-D: function "SD_DMAEndOfTransferStatus" declared implicitly
sdio_sd.c(1552): warning:  #223-D: function "SD_DMAEndOfTransferStatus" declared implicitly
sdio_sd.c(2772): warning:  #177-D: label "__return" was declared but never referenced```

这一步只有警告，没报错。

将rtconfig.h中定义，#define RT_USING_DFS，其它未改动。用Arda Scons编译，警告加报错：

```> armcc -o buildspstartup.o
> "startup.c", line 102: Warning:  #223-D: function "rt_hw_sdcard_init" declared implicitly
>   	rt_hw_sdcard_init();
>   	^
> "startup.c", line 108: Warning:  #223-D: function "rt_hw_rtc_init" declared implicitly
>   	rt_hw_rtc_init();
>   	^

```

我有点不太明白的是，
1）	Keil和Scons的结果为什么会不一样？我应当用哪个？
2）	RT_USING_DFS 跟ethernetif.h有什么关系，为什么Scons要ethernetif.h？

最重要的是，我的操作步骤没错吧？如果是bug，有改好的用最好，要不然我就自己折腾了。多谢，多谢

PS，STM32F2跟F4的外设是不是一样的？也就是说F2的driver基本可以到F4跑？
