[U-Boot] S3C2440 "usb start" and then "usb stop" cause nand operate failure.

Hi, guys here. for u-boot-2010.03(also u-boot-2010.05 I belive) on s3c2440, if I "usb start" and then "usb stop", all of the nand operate will report failure. I look into the u-boot code, and found that it seems something wrong in s3c24x0 usb code, see below. >From s3c2440 and s3c2410 datasheet
