This patch implements write support to usb device with raw partition. It will be useful for filesystem write support to usb device from u-boot in future. Tested with writing kernel image to raw usb disk & booting with usb read command into ram. [Note: run usb part to get info about start sector & number of sectors on a partition for usb write operation.] Signed-off-by: Mahavir Jain <mjain@marvell.com>
