> Subject: [PATCH 5/5] drm/i915: Enable fastboot across the board
>
> From: Ville Syrjälä
>
> There's nothing magical about vlv+ platforms vs. fastboot.
> If it works somewhere it should work everywhere, assuming we've not missed
> any crucial state checks. That seems unlikely on
> older platforms with less state to check anyway.
>
> Just enable fastboot across the board, and the remove the remnants of the
> optional stuff (we already removed the modparam for
> fastboot anyway).
