External dts building

Hello All,

is there a way to pass a dts file without touching the arch/arm/boot/dts/Makefile?

On Buildroot we support the possibility to pass an external dts by copying it to the uboot sources to be built but since uboot version 2020.01 it doesn’t work anymore.

So I’ve proposed a patch to prepend the dts file in the Makefile above, but this has drawbacks, like we reconfigure(it keeps adding files every time).

So I ask you, is there a more canonical way already to achieve this?

Thanks in advance Best regards
