Once you enable USB and SD boot ("crossystem dev_boot_usb 1" or sth like
that) you are able to boot from internal eMMC (Ctrl-D) or SD (Ctrl-U) or
USB 2.0 port (also Ctrl-U). U-Boot stored in SPI flash does not have
support for USB 3.0 port.
But you can boot kernel from eMMC with rootfs on USB 3.0 hard drive.
The hard drive doesn't boot, even when on the USB 2 port. It
seems this cannot be done, so I've now arranged it to load
the kernel from flash and mount the root disk from the hard disk.
