I got a bit farther along.  The U-Boot that gets built by the Yocto setup is
configured to run from NOR FLASH.  Once I got that programmed using the ATK tools,
I was able to get into U-Boot.

I then tried to boot Linux over the network, using my SD card as the file system.
Sadly, this only got as far as uncompressing the kernel.  I'll keep trying.
