The data 12 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 for 15 controlling shared resources. Depending on the board configuration the shared 16 resource properties may change. These properties are dynamically probed by the 17 remote processor and made available in the shared memory. 18 19maintainers: 20 - Bjorn Andersson <bjorn.andersson@linaro.org> 21 22allOf: 23 - $ref: reserved-memory.yaml 24 25properties: 26 compatible: 27 const: qcom,cmd-db 28 29required: 30 - reg 31 32unevaluatedProperties: false 33 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
