Can I have the sources for System Max V on Arria 10 dev kit board (U16)?

Since all peropheral connected to A10 through the MAX V, I would like to know how it is connected to these peripheral.

to be more specific I would like to connect UART DB9 (J35) to A10 (U23).

So I need Either a document to suggest the pins in/out of A10 (U23) to connect this peripheral.

thanks
