Hi, thanks for the info. We have solved this architecture (hardware generation) issue in a component called octopus with a Kconfig generation choice, ex. 2GEN or 3GEN. The component contains many small systemd services that execute Bash scripts, so it already has many Kconfig selects on various command line tools. As not all services run on all hardware generations, ex. Only 3GEN[1][2] has a TPM chip: select TPM2_TOOLS if RUNTIME && OCTOPUS_3GEN It's one of these services that require uhubctl so now we do: select UHUBCTL if RUNTIME select GCCLIBS_ATOMIC if RUNTIME && OCTOPUS_2GEN /Bruno [1] https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/imx7d-flex-concentrator.dts [2] https://elixir.bootlin.com/barebox/latest/source/arch/arm/dts/imx7d-flex-concentrator-mfg.dts
