NetBSD does not, u-boot does. This is configured in the u-boot environment
(which typically is the default u-boot env as the images do not come with
a saved env).

So it depends on your u-boot, and you can look at more details when you
interrupt the boot process early and ask u-boot to "printenv".

The images are generic (that is: everything is the same in all images), only
the u-boot (and other files/blobs needed for booting) differ.
