文件描述了2410和2440的区别,因2410和2440的差别很小，所以移植工作量非常小。仅需修改：配置文件config.h、启动文件initcpu.s，uart模块、nand芯片驱动模块，键盘模块key-hard.c。-Document describes the difference between 2410 and 2440, due to the difference between 2410 and 2440 is small, so the workload transfer is very small. Only changes: configuration files config.h, startup files initcpu.s, uart module, nand chip driver module, the keyboard module key-hard.c.
