zcu102 rev1.1 compare to rev1.0 is using by default different DDR memory which requires different configuration. The reason for adding this file to Linux kernel is that U-Boot fdtfile variable is composed based on board revision (in eeprom) and dtb file should exist in standard distibutions for passing it to Linux kernel.
