    remoteproc: add a rproc ops for performing address translation · a01f7cd6
    Suman Anna authored
    The rproc_da_to_va API is currently used to perform any device to
    kernel address translations to meet the different needs of the remoteproc
    core/drivers (eg: loading). The functionality is achieved within the
    remoteproc core, and is limited only for carveouts allocated within the
    core.
    
    A new rproc ops, da_to_va, is added to provide flexibility to platform
    implementations to perform the address translation themselves when the
    above conditions cannot be met by the implementations. The rproc_da_to_va()
    API is extended to invoke this ops if present, and fallback to regular
    processing if the platform implementation cannot provide the translation.
    This will allow any remoteproc implementations to translate addresses for
    dedicated memories like internal memories.
    
    While at this, also update the rproc_da_to_va() documentation since it
    is an exported function.
