Hello Krzysztof,

I've checked as follows:

$ make ARCH=arm64 CHECK_DTBS=y W=1 freescale/s32g274a-evb.dtb 
freescale/s32g274a-rdb2.dtb freescale/s32g399a-rdb3.dtb
   DTC [C] arch/arm64/boot/dts/freescale/s32g274a-evb.dtb
   DTC [C] arch/arm64/boot/dts/freescale/s32g274a-rdb2.dtb
   DTC [C] arch/arm64/boot/dts/freescale/s32g399a-rdb3.dtb


Best Regards,
