I am porting Linux to a new SC589 platform that doesn't implement a softconfig (MCP23017 port expander) but most of the drivers in the Yocto release use this mux and it's really embedded in the code. I've tried commenting all the softconfig stuff out but bitbake is still barking at me as follows...

Any help would be appreciated. Just to say again, I believe the softconfig stuff has been commented out of the source files in the git folder.
