I tried that, but didn't have much luck on my beaglebone - the kernel
just seems to hang (with no output at all on the console).

I did notice that beagle_start.S didn't contain any "setenv be"
instruction, so I added that similar to how it's done in rpi2_start.S
- but then I only get a "data abort":

## Transferring control to NetBSD stage-2 loader (at address 80300000) ...
