Subject: [PATCH v3 0/3] QCOM SCM Download mode support
Date: Wed, 9 Aug 2017 13:10:30 -0700 [thread overview]
Message-ID: <20170809201033.4967-1-bjorn.andersson@linaro.org> (raw)
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
