Enable the support for download mode to collect the RAM dumps if system crashes, to perform the post mortem analysis. During the bootup, bootloaders initialize the SMEM. However the bootup after crash, SMEM will not be intialized again. If the memory for the SMEM is not reserved, linux consumes that region, which leads to the loss of SMEM data. So, during the next bootup after crash, bootloaders will hang due to invalid data present in the SMEM region. Due to this, added the SMEM support along with this series. This series depends on the IPQ5332 baseport patches https://lore.kernel.org/linux-arm-msm/20230130114702.20606-1-quic_kathirav@xxxxxxxxxxx/T/#t Kathiravan T (3): dt-bindings: mfd: qcom,tcsr: add compatible for IPQ5332 arm64: dts: qcom: ipq5332: enable the download mode support arm64: dts: qcom: ipq5332: add SMEM support .../devicetree/bindings/mfd/qcom,tcsr.yaml | 1 + arch/arm64/boot/dts/qcom/ipq5332.dtsi | 20 +++++++++++++++++++ 2 files changed, 21 insertions(+) -- 2.17.1
