How to correctly load a driver without device tree?

[Gajjar Akash]

Hi there,

If you are using systemd, you can make your own Target like early.target
and load modules without udev.

But you need to load modules without device tree, I guess that's not
possible.

your system is booting without device tree?

Thanks,
Akash
