Plenty, though understanding the details requires a bit knowledge about the respective platforms. If you look at configs/arm64/zynqmp-zcu102-linux-demo.c, e.g., you can see that it gets a UART assigned by handing over the MMIO region and (IIRC) GIC IRQ 54. But, as I already explained, there can be more complex challenges when you also need to enable / clock the respective device, and those controls are shared with the root cell.
