天嵌提供的GPIO驱动没什么用,限制性太大了, 这个是基于天嵌2440的GPIO驱动, 通过输入子系统event层,编写的gpio标准键盘驱动 除了板上的4个按键,从GPIO外展增加了两个按键, 为与PC上调试,定义为F1到F6-EmbbedSky provided gpio driver is useless, too restrictive, this is based on the TQ2440, through the input subsystem event laye

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
