    Subject[PATCH 0/4] Update K3 DSP remoteproc driver for C71x DSPs
    Date
    Hi All,

    This series adds support for a new next generation 64-bit TI DSP based on
    the TMS320C71x CorePac processor subsystem called the C71x. The support is
    enabled through couple of enhancements to the remoteproc core (primarily to
    support a 64-bit trace resource entry), and does depend on the K3 DSP
    remoteproc driver posted earlier today [1].

    The loading support leveraged the 64-bit ELF loader support code added by
    Clement and already staged on the rproc-next branch. I am posting this
    series separate from the C66x series because of the new 64-bit resource
    type enhancement needs (patches 2 and 3). I have leveraged the existing
    resource types as is by introducing a new version element, and am open to
    ideas if it is desired to just define it as a separate resource type.

    The C71x DSP boots using firmware segments loaded into the DDR with a 2 MB
    aligned address requirement on the boot vectors. There is no support for
    internal memory loading, and all internal memories shall be used as fast
    RAMs/scatchpads by the firmware executing on the DSPs. IPC is through the
    virtio-rpmsg transport. There is no support for Error Recovery, Power
    Management or loading into on-chip SRAMs at present.

    Following is the patch summary:
    - Patch 1 updates the K3 DSP bindings for C71x cores
    - Patch 2 introduces a concept of version element into existing resource types
    - Patch 3 adds support for a new 64-bit trace resource entry
    - Patch 4 enhances the K3 DSP remoteproc driver for C71x

    regards
