Say Y here if you want to use the Xilinx uartlite serial controller.

Hi!
Doesn't the Zynq use xilinx_uartps ? (which in turn is actually a Cadence UART)

You can add this soft IP to programmable logic.
It means 2 uartps are hard blocks in the zynq and then you can add unlimited number
of these uartlite drivers or ns16550 to PL.
