I run below command, have not found above warning
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j8 CHECK_DTBS=y freescale/imx95-15x15-evk-pcie0-ep.dtb
DTC [C] arch/arm64/boot/dts/freescale/imx95-15x15-evk.dtb
DTC arch/arm64/boot/dts/freescale/imx-m2-pcie.dtbo
DTC arch/arm64/boot/dts/freescale/imx-pcie0-ep.dtbo
OVL [C] arch/arm64/boot/dts/freescale/imx95-15x15-evk-pcie.dtb
OVL [C] arch/arm64/boot/dts/freescale/imx95-15x15-evk-pcie0-ep.dtb
Anything wrong?
