Read problem using LPDDR2 uniphy

The afi_rdata_en and afi_rdata_en_full appear for me when I use just Uniphy. I use my own controller not the Altera controller. If they are not there on the top level then you probably don't need to control them. Your problem sounds different to what I reported. Check the timing of your signals match exactly what is in the EMi handbook for your setup. You can also simulate the example design that is generated from the megafunction generation. Look at how it controls the signals.
