Registers:
Enable Reg: enable the pin as a function or just a GPIO pin.
Direction Reg: I/O, input or output. (defined by hardware)
Output Reg: Activity, activize utility of the GPIO pin when high or low current. (0 or1)
Input Reg: The reg for input data. (device ==> cpu)
Input/Output:
Output: cpu ==> device (ex: led)
Input: device ==> cpu (ex: reset button)

U-Boot Command 架構
Ex:
int setGpioA(u32 pin, u32 value);
int unknown_GPIO(cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) //argc 參數個數
{

{
setGpioA(10, 0);
}
else if((strcmp(argv[1], "off") == 0) || (strcmp(argv[1], "OFF") == 0))
{
setGpioA(10, 1);
}
return 0;
}
int setGpioA(u32 pin, u32 value)
{
volatile unsigned int reg = 0x01 << pin;
if(value == 1)
{
*((volatile unsigned int *)0x74000000) |= reg; //取暫存器位址之值

}
else
{
*((volatile unsigned int *)0x74000000) &= ~reg;
}
return 0;
}
U_BOOT_CMD(

Mosquito Killer
The application emit a very unique high frequency sound (ultra sound) that insects dislike. The pitch of the sound is so high that most humans will not notice anything.
* Not all devices support the high frequency sound
聲音即是一種能量。正常的人耳聽力範圍極限約在20kHz~20000kHz之間，此app能產生人耳聽覺範圍外的超高音頻，利用其能量達到驅趕蚊蟲的功效。
*建議將手機音量調大，以提高功效
*並非所有手機的音訊裝置都支援此超高音頻，正常情況下執行此app，人耳是聽不到聲音的。若執行app時手機發出任何聲音，表示您的手機不支援。
