Your pinmux request for MAC1 failed. What does your devicetree look like?

Building a kernel with CONFIG_DEBUG_PINCTRL=y might help.

Same issue here

This kind of failure isn't entirely surprising in light of the above.

Are you building the right image for your hardware? What platform are
you trying your build on? Is it actually an s2600wf? What source tree
are you building from? Beware that Intel have an OpenBMC fork that
contains patches that they haven't yet got merged into upstream
OpenBMC that may provide better support for their platforms:
