I've now done a full cross debootstrap on the host to work around the
kernel BUG, adding the kernel modules from 4.16-rc5 manually to the rootfs.
Interestingly, U-boot or the kernel don't seem to see the ethernet device
at all. Also, the ATF is complaining about setting up the PMIC which may be
related?

If I try to manually "modprobe dwmac-sun8i" once booted then the module
loads but nothing appears in the kernel log and I get no network interface,
so presumably it can't see the device.

This is with the DTB from 4.16-rc5.
