通过固件传递自定义启动参数给内核

代码如下:

static int data_x = 1024;

static int data_y = 768;

static int __init datax_setup(char* str){
    data_x=simple_strtol(str,NULL,0);
    return 0;
}
__setup("data_x=", datax_setup);
static int __init datay_setup(char* str){
    data_y=simple_strtol(str,NULL,0);
    return 0;
}
__setup("data_y=", datay_setup);
