Device Tree dts ... multiple copies?

Hi, 

 

I'm building Linux 5.4 for an i.mx6ul-evk, I'm new to yocto and am somewhat confused by the file structure.  I succeeded in building a core-image-base, but now I want to modify the device tree and I don't know which .dts file to modify.  Here are all of the imx6ul-14x14.dts files that I have, which appear to be duplicates:

 

/opt/yocto/imx-yocto-bsp/build/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabi/linux-libc-headers/5.4-r0/linux-5.4/arch/arm/boot/dts/imx6ul-14x14-evk.dts

 

/opt/yocto/imx-yocto-bsp/build/tmp/work/x86_64-linux/qemu-native/4.1.0-r0/qemu-4.1.0/roms/u-boot/arch/arm/dts/imx6ul-14x14-evk.dts

 

/opt/yocto/imx-yocto-bsp/build/tmp/work/x86_64-linux/u-boot-tools-native/1_2019.07-r0/git/arch/arm/dts/imx6ul-14x14-evk.dts

 

/opt/yocto/imx-yocto-bsp/build/tmp/work/cortexa7t2hf-neon-mx6ul-poky-linux-gnueabi/linux-imx-headers/5.4-r0/git/arch/arm/boot/dts/imx6ul-14x14-evk.dts

 

/opt/yocto/imx-yocto-bsp/build/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/1_2019.04-r0/git/arch/arm/dts/imx6ul-14x14-evk.dts

 

/opt/yocto/imx-yocto-bsp/build/tmp/work-shared/imx6ulevk/kernel-source/arch/arm/boot/dts/imx6ul-14x14-evk.dts

Which of these should I modify to change the device tree?
