No, you can't hard-code an ethaddr in.

These are really close together. And I imagine mirror the usual values
on 32bit platforms. Maybe it's time to move them around a bit for more

We also shouldn't have to play "stop relocating the DT" games on
aarch64, right? Since all memory is visible and that's why we have to
do those games on aarch32.

You aren't using $fdt_addr/$kernel_addr here and probably should?
