I’m pretty sure that’s not possible, since I’ve never built ARM
kernels in this particular VM before :-)

From the fdt command in the loader I can see it’s the first device
mentioned, so that’s not it.

loader> fdt ls
Using DTB provided by U-Boot at address 0x80000100.

	*snip*

A verbose boot gives me:

ofwbus0: <Open Firmware Device Tree>
simplebus0: <Flattened device tree simple bus> on ofwbus0
simplebus0: <interrupt-controller at 48200000> mem 0x48200000-0x48200fff compat ti,aintc (no driver attached)

Ok, so this is a problem.
