Yeah...I started by writing this patch with device tree specifically
(of_get_mac_address()), and then later found that there were generic
"device" helpers for this, which can assist with other sorts of
firmware nodes. It was easier to put a name on a device tree patch
than on a "device" patch. I suppose "system firmware" might be a
better description?

Let me know if you have a better way to clarify. I can resend with a
slightly modified subject (s/firmware/system firmware/), or let Kalle
do it, if that's the only thing to change.
