Port u-boot using walnut code as an example.
Copy the Linux walnut code to foo_board.[c|h]. Remove what you don't need
from the files. Modify other things accordingly. Update the
Kconfigs/Makefiles.
Unless the hardware is buggy, it should be very straightforward. You
can even proof of concept things by loading vmlinux from your JTAG
debugger and setting r3-r7 appropriately...skipping the firmware stage.
