Ha, you haven't seen the full notes on my other patch have you?
https://lists.yoctoproject.org/g/meta-ti/topic/96386295#15613

I switched these to be COMBINED_FEATURES. Like alsa, they require both 
a machine feature and a distro feature to be present to actually patch 
the packages we need. In this way patches become opt-in and software 
rendering becomes the default unless someone specifically wants a 
distro with powervr-rogue-graphics patches.

In addition if they have a distro that wants powervr-rogue-graphics and 
they are compiling for a machine that doesn't have that feature then it 
will also fall back to software rendering.

The only issue this doesn't solve is when someone wants to hack recipes 
like gstreamer to introduce pseudo graphics support or bundle random 
pieces of the graphics stack without including all of it, but arguably 
that should be a specialized package group or new layer anyway.
