Hello, I found when I do
make ARCH=arm CROSS_COMPILE=arm-none-eabi- vexpress_ca9x4_defconfig make ARCH=arm CROSS_COMPILE=arm-none-eabi- -j24 , the file dts/dt.dtb.S is executed (looks like linker script) and dts/dt.dtb file is placed in the u-boot.bin binary. Can anyone tell me how this dts/dt.dtb.S is included during the build and how dts/dt.dtb file is generated? Any comment will be deeply appreciated. Thank you. Chan Kim
