For u-boot this should be ok but it is not the part of kernel DT binding.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/firmware/xilinx/xlnx,zynqmp-firmware.txt?h=v5.3-rc8

Also adding simple-bus in u-boot DTS file would cause issues ok kernel
side when DT from u-boot is used in Linux.

My expectation is that we should move all functionality which we have in
platform code to this driver.

Thanks,
