It's simple: - first stage boot can be sent over the otg - using dfu to flash the u-boot.img, kernel .. etc dfu is another way to upload and write second stage or what you want. I don't see the point to don't have this option. We have merged USBETH spl support and dfu is more useful. ./usb_load MLO.flash ./dfu-util ...
