Another place this doesn't work (which is where it doesn't work for me)
is when the console is already open and I can't easily take it away to
shoot over the next stage via Y-MODEM.
Would it be possible to implement having the next stage also be sent via
imx_usb_loader? ie there's examples today of doing u-boot.imx + kernel
+ initrd via imx_usb_loader, so what would be needed for SPL +
u-boot.img (+ kenrel + initrd) via imx_usb_loader? Thanks!
