QEMU-booting a Nard image

[Ronny Nilsson]

Hi Richard
I'm guessing here since I haven't used Nard in qemu myself, but check that 
you've got device tree working in qemu. RPi kernels won't work without it.

I guess you already know this, but the sdcard image can be loop mounted with
	mount -t vfat sdcard.img /mnt/ -o loop,offset=8192
