USB support (ehci) at the bootloader and then the driver for the
device you want to use.

u-boot supports quite a few ethernet devices, so I believe making usb
to work would probably be the only thing needed.

Even if not fully able to boot from USB, we can have at least a
minimal u-boot/SPL that would deliver DFU support, this way you could
still push another boot loader later on.
