When implementing an baseboard specific init handler, we will get a warning about unused 
tqma6_ecspi1_pads and tqma6_ecspi1_cs, or did I miss something?

Just as a thought (not ready): Could we supply CS initialisation data via defines in the
baseboard config header and append it to the tables if needed?
