     title: Qualcomm Command DB
     
     description: |
      Command DB is a database that provides a mapping between resource key and the
      resource address for a system resource managed by a remote processor. 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.
