Looks like the K3 u-boot is pre-setup so that you can do all sorts of interesting things.
I don't know if this u-boot can init the wired (over USB) or wireless networking, but even if it can't you could still transfer and run a memory resident "rescue kernel" as an s-record image.
Might not be the fastest way to load a kernel and filesystem image, but if nothing else can be done...
