为UPNET2410添加USB支持

添加USB驱动支持
SCSI选项,USB相关选项打开.
出现

usb 1-1: new full speed USB device using s3c2410-ohci and address 4    

usb 1-1: device descriptor read/64, error -62                                  

usb 1-1: device descriptor read/64, error -62                                  

usb 1-1: new full speed USB device using s3c2410-ohci and address 5            

usb 1-1: device descriptor read/64, error -62                                  

usb 1-1: configuration #1 chosen from 1 choice

经过查询下面方法可以解决

在driver/usb/host/ohci-s3c2410.c中添加如下代码

unsigned long upllvalue = (0x78<<12)|(0x02<<4)|(0x03);


while (upllvalue != __raw_readl(S3C2410_UPLLCON))
{
__raw_writel(upllvalue, S3C2410_UPLLCON);
mdelay(1);
}

挂载的时候还有可能出现不支持UTF字符集问题.在file system 的 native language support中添加对UTF支持就可以.主要是DOS/FAT/NT file system 中的字符集在本地语言支持中有就可以.
