From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Replace the ad-hoc plane indexing scheme used by the frontbuffer
tracking with enum plane_id.
The old video overlay not being part of the plane_id namespace
will just be given the high bit.

I would feel safer with a BUILD_BUG_ON to catch plane_id overflowing
INTEL_FRONTBUFFER_BITS_PER_PIPE (-1 for the overlay reservation).

The conversion looks straightforward nevertheless, and indeed no reason
to have move than one indexing id for a plane.

I'm curious why the bit corresponding to PLANE_SPRITE0 is not re-used
for the overlay. From a cursory read seems like platforms with overlays
and sprites are mutually exclusive.
Related question, how different is this overlay from the sprite planes?

Currently yes, but maybe not in the future. I still have dreams of
exposing all the planes on these platforms, which would mean having
at least one sprite plane that's not the video overlay. I haven't
really figured out how to make it all work out nicely with enum
plane_id though as that's a per-pipe thing and the planes on the
old hw are not necessarily tied to a single pipe. Perhaps one
option would be to assign the plane ids globally, ie. PRIMARY==A,
PLANE1==B, PLANE2==C, etc. Not sure if that would actually work out
though.

Very different. I would like to expose it as a drm_plane eventually,
but there's a bit of actual work involved to convert the overlay
register updates to use mmio, and to handle the render cache
reconfiguration (which still involves stuffing MI commands to the
ring) in a decent way.
I do have a basic mmio conversion sitting on some branch somewhere,
but I don't think I got it to look as nice as I'd like. Plus it's
probably bitrotted enough by now that it needs some rework anyway.

Actaully we'll be going past that BITS_PER_PIPE-1 limit real soon
now, but the BITS_PER_PIPE will be sufficient for some time I think.
So I think I'd just rather ignore the overlap between the plane_id
and the overlay because that's not going happen on actual hardware.
But I think asserting that BITS_PER_PIPE is sufficient is a good idea.
Just need to figure out where to put it. There's no init function
or anything like that in the frontbuffer tracking code, so that's
not going to work. I guess one option would be to include the
assert in the INTEL_FRONTBUFFER() macro itself.

Pushed this as is to dinq. Thanks for the review.
I'll send that BUILD_BUG_ON() as a followup.
