It seems to work fine. There is plenty of boot up chatter on the console, the various green status lights on the board light up. There is no smoke. No fire. After a suitable amount of time the red status LED begins blinking.
To actually get to the U-Boot prompt is easy, you just type 'd' quickly after the board boots. I am almost always able to get this my first time.
The first line is exactly the same as the first board I worked with.
