Mesa almost always uses proprietary firmware. The fail0verflow guys did some work last year to at least document it for the PS4's GPU to patch a bug. But the upstream Radeon Mesa guys are really hesitant to upstream it to avoid pissing off AMD. https://github.com/fail0verflow/radeon-tools/tree/master/f32

Of course that's all sorta orthogonal because that's all not really microcode or firmware in the classic definition, but just "code for an embedded processor I don't want to document."
