[PATCH meta-rockchip 1/2] mesa: enable lima on all rk3328 boards

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@cherry.de>

lima is the open-source implementation for the GPU found on RK3328, it
is therefore not specific to the Rock64 but all boards based on the
RK3328.

[PATCH meta-rockchip 2/2] mesa: build panfrost for RK3568 boards

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@cherry.de>

The RK356x SoC family (of which we currently only support RK3568) has a
Bifrost GPU that is supported by open-source Panfrost Linux kernel and
Mesa drivers, therefore let's build mesa with Panfrost support for
RK3568.

I have a couple rk3328-based boards, but the rock64 is the only one of these
that has a video output device (hdmi). So I guess if someone really wants to
build a graphics-based image for an rk3328-based board that doesn't have a
video dongle, then I guess they would want panfrost too (?)

It's been a long time since I've done any graphics stuff, I have a rock-3a
that is rk3568-based but couldn't get x11 nor weston/wayland working. I
probably need to do more fiddling.

Neither of these patches interfere with the build so I'm okay adding them.
Would you also want them on scarthgap as well?

The NanoPi R2S and RockPiE seem to be the only ones with no video output 
at all (the display subsystem is even disabled in the DTS for the NanoPi).

In any case, it should technically be possible to use the GPU without 
any video output, though I haven't managed to make my RK3588 boards work 
without DSI or HDMI support with Panthor so no clue how this should work :/

Not everything done by the GPU is for displaying stuff (could be used 
for maths stuff, openCL and the likes, on headless systems).

I only use kmscube for my tests. You basically only need to make sure 
that the renderer isn't LLVMPipe or swrast and you're good to go.

I have no personal or professional interest in those patches so up to 
you, it's just that I'll need some patches for RK3588 Panthor once we 
publish a downstream kernel with support for it (there's already one but 
I don't want people to start using it, so not creating a recipe just now 
:) ), and this patch series will then probably conflict with it in the 
git context, but nothing too difficult to deal with :)

So, up to you!

Cheers,
Quentin

Applied to meta-rockchip, master branch. Thanks!
