The version number tells us it is 131 patches ahead of U-Boot 2017.05-rc3. Dirty means the source contained uncommitted changes. Unfortunately this is not a reproducible test environment. Could you, please, provide the build recipe to reproduce the U-Boot BayLibre is using? Would it be possible to use mainline U-Boot in kernelci for this board?
