The data +is stored in a shared memory region and is loaded by the remote processor. + +Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for +controlling shared resources. Depending on the board configuration the shared +resource properties may change. These properties are dynamically probed by the +remote processor and made available in the shared memory. + +The bindings for Command DB is specified in the reserved-memory section in +devicetree.
