This might be true in practice for this specific SoC just due to these being the only devices made, but in general, "boots Linux at EL2" does not automatically imply "does not use smp2p/remoteprocs" (see Glymur; and earlier laptops with hacks that happily use ADSP under EL2) so the dtsi that includes all remoteprocs being called "el1" is quite strange IMO > Move them into sm8650-el1.dtsi, included by the EL1 boards, and drop the > node deletions from the Deckard dts. > > Signed-off-by: Neil Armstrong > --- > .../boot/dts/qcom/sm8650-ayaneo-pocket-s2.dts | 1 + > arch/arm64/boot/dts/qcom/sm8650-el1.dtsi | 775 +++++++++++++++++++++ > arch/arm64/boot/dts/qcom/sm8650-hdk.dts | 1 + > arch/arm64/boot/dts/qcom/sm8650-mtp.dts | 1 + > arch/arm64/boot/dts/qcom/sm8650-qrd.dts | 1 + > arch/arm64/boot/dts/qcom/sm8650-valve-deckard.dts | 21 - > arch/arm64/boot/dts/qcom/sm8650.dtsi | 774 +------------------- > 7 files changed, 801 insertions(+), 773 deletions(- > [..] Thanks, ~val
