It looks pretty similar at the moment, I've been meaning to clean those
<br>
patches up and send them upstream but Paul has beaten me to it. The main
<br>
difference so far is how the console is setup. For booting cache contained I
<br>
was using a device tree pointing at a standard UART driver and enabling the
<br>
standard OF platform device tree probing.
