ZC706-FMCOMMS5 Hw design:Use of enabled IIC in Zynq

Hi 

I am working on ZC706 with FMCOMMS5 board, for this I am using the hardware taken from Github. I am using axi_ad9361  IP. I wanted to communicate with EEPROM(uses IIC interface) through PL, I am not getting what is the purpose of enabling iic driver in zynq, especially while working with No-OS drivers of FMCOMMS5.Any reply would be helpful.

Thanks in advance
