The data12 is stored in a shared memory region and is loaded by the remote processor.13 14 Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for15 controlling shared resources. Depending on the board configuration the shared16 resource properties may change. These properties are dynamically probed by the17 remote processor and made available in the shared memory.18 19maintainers:20 - Bjorn Andersson <bjorn.andersson@linaro.org>21 22allOf:23 - $ref: reserved-memory.yaml24 25properties:26 compatible:27 const: qcom,cmd-db28 29required:30 - reg31 32unevaluatedProperties: false33 34examples:35 - |36 reserved-memory {37 #address-cells = <1>;38 #size-cells = <1>;39 ranges;40 41 reserved-memory@85fe0000 {42 reg = <0x85fe0000 0x20000>;43 compatible = "qcom,cmd-db";44 no-map;45 };46 };47
