Will do.  But I'll have to do this in a separate patch then the
grouping of STS_ and FFCR_ defines you're referring to below since it
will also require changes to the .c files.

TMC_STS_FULL is not added here because at this point it is not used by
the code - it is only added later when it is useful.  Please get back
to me if I missed your point.
