Would it be difficult to turn this into a function ?
You can likely implement some function like int fsl_has_erratum(const unsigned int erratum) and then do the string concatenation with snprintf().
Do you suspect any possible issue with macro implementation, or your comment is for reducing the size of U boot by making it a function?
