This enables kernel developers to enable "download mode", a mechanism for
entering a debug state to "download" memory content following a unexpected
warm-restart; e.g. security violation by accessing a protected register.

Bjorn Andersson (3):
  firmware: qcom: scm: Expose secure IO service
  firmware: qcom: scm: Expose download-mode control
  arm64: dts: qcom: Specify dload address for msm8916 and msm8996
