Just a side note - I can't see any reason to duplicate the whole dts file if it is just the same - you can simply #include "zynq-zturn.dts" and then change/rewrite things. Second thing is that myir,zynq-zturn is not even listed in any yaml binding file that's why dtbs_check will fail. I expect you use standard boot flow via u-boot which can detect and update memory size automatically for you. It means for kernel you can even place there <0 0> and u-boot will fill it. Just a summary I don't think it is worth to add support to this board in Linux. And in U-Boot you should enable memory autodetection and you will get support for this lite board for free.
