 I should have asked before, but: where do those binaries come from? Are they
from the mali-sunxi package? Or not yet packaged in Buildroot?

 foo-bar sorts after foo, so swap these two lines.

 I guess with 'binary blobs' you mean the OpenGL libraries, which are only
provided as binaries? 'binary blobs' to me sounds like something like firmware
blobs: is put in your rootfs but doesn't run on the target processor. So I'd
rephrase as: ... together with the corresponding userspace OpenGL libraries,
which are provided as binaries only.

 And preferably also explain where you can get those.

 Shouldn't the r6p2 be configurable? That can be done in a later patch, though.
