ah, the -rt type trick ;-)
i'd suggest one more small detail:

could you rename it to trace_type() - that way the initialization could
be written in a more compact way as:
> + struct trace_mmiotrace_map *field = trace_type(field, entry);
[ NOTE: there's namespace clash with a local symbol in ./trace_irqsoff.c
and a trace_type enum as well ]
