You don't need u-boot.imx to boot the board with imx_usb_loader. Check the README update that Stefano did with this commit:

 imx_common: check for Serial Downloader in spl_boot_device

 Check for bmode before reading the boot device
 to check if a serial downloader is started,
 and returns UART if the serial downloader is set,
 letting SPL to wait for an image if
 CONFIG_SPL_YMODEM_SUPPORT is set.

 This allows to load again a SPL based board
 with imx_usb_loader together with a tool
 such as kermit.

This is not particularly what I want to do. I want to load the u-boot.img directly via the imx_usb_loader. The kermit method is unacceptably slow for a production environment.
