Any pointers or > suggestions would be appreciated. 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. -Matt
