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
