There are some unobvious issues with adding PVR support to Mesa via a bbappend: 1. We need to mark mesa package as machine-specific, due to differences in builds between SGX, Rogue and software-rendering 2. We also need to then mark mesa package as providing safe ABIs (EGL/GLES/GBM) in order for all generic dependent packages to not be treated as machine-specific, allowing their re-use across different machines of the same architecture But doing the above alters the upstream mesa package and changes its signatures even when not building for TI platforms, which is a Yocto Project compliance violation. In order to resolve this issue, convert Mesa bbappend, that adds PVR support, into its own standalone alternative provider, called mesa-pvr and allow selecting it with PREFERRED_PROVIDER settings.
