1.因为这个mach-mini2440.c是从mach-smdk2440.c处复制过来的，mach-smdk2440.c中未对nand作处理，但这里我们作处理啦，所以应在文件中加入相应的头文件6 J; J J, e1 {0 X3 \+ r

查找资料发现有这样的说明：
# e" L! s4 F' p2 ~: p 这个问题是由于arch/arm/mach-s3c2440/mach-mini2440.c中nand flash controller相关配置数据被声明为__initdata属性造成的。这部分数据会在根文件系统挂载后被释放，但事实上它们还会被nand flash driver用到，因此就出现了memory access问题。解决的办法是把arch/arm/mach-s3c2440/mach-mini2440.c中下列几行中的__initdata声明去掉：5 p$ j' b: A) r; v: ^
