Initially port over what is there already. Later maybe include in the compiler stuff like scoped RTTI (not just published alone) and "customattributes" if there is need for that level of compatibility. Also, adding more methods on the current interface is possible too. It is more than just a readable substitute for TypInfo.
At the present state of fpc compiler it is technically imposible to port 
delphi rtti unit. To do this you need first to implement the next 
compiler features:

1. Extended records (methods, class operators)
2. Generics as in delphi
3. Attributes

Once I tried to implement extended records in the compiler but the 
changes were too big for the time I had and I had left that idea for the 
better time.
