[Mesa-dev] [PATCH 0/9] panfrost: Initial sRGB support

This series adds new flags and formats relevant to sRGB textures and
framebuffers, which cause quite a bit of refactoring. One 'hidden gem'
here is support for rendering to Mali's uncompressed tiled format
(Utgard-style tiling). I suppose earning those magic bits is a tradeoff
for not getting AFBC on sRGB FBOs.

Supporting sRGB in blend shaders will be a bit more work, out of scope
for this initial series.

I'm not terribly interested in sRGB quite yet (it's ES3 class), but it's
the one unadvertised feature required to bump our desktop version back
to GL 2.x, which matters for glamor.
