arm64: dts: qcom: Specify dload address for msm8916 and msm8996 (1f34d644) · Commits · 戴 / test

On msm8916 and msm8996 boards a secure io-write is used to write the magic for selecting "download mode", specify this address in the DeviceTree. Note that qcom_scm.download_mode=1 must be specified on the kernel command line for the kernel to attempt selecting download mode. Signed-off-by:
