  • 4f6fd5a03   remoteproc: Drop dangling find_rsc_table dummies ... Browse Code »

    As the core now deals with the lack of a resource table, remove the
    dangling custom dummy implementations of find_rsc_table from drivers.

  • 0f21f9cc9   remoteproc: Merge rproc_ops and rproc_fw_ops ... Browse Code »

    There are currently a few different schemes used for overriding fw_ops
    or parts of fw_ops. Merge fw_ops into rproc_ops and expose the default
    ELF-loader symbols so that they can be assigned by the drivers.

    To keep backwards compatibility with the "default" case, a driver not
    specifying the "load" operation is assumed to want the full ELF-loader
    suit of functions.

    Declare rproc_ops structures as const as they are only passed as an
    argument to the function rproc_alloc. This argument is of type const, so
    rproc_ops structures having this property can be declared const too.
    Done using Coccinelle:

    @r1 disable optional_qualifier @
    identifier i;
    position p;
    @@
    static struct rproc_ops i@p = {...};

    @ok1@
    identifier r1.i;
    position p;
    @@
    rproc_alloc(...,&i@p,...)

    @bad@
    position p!={r1.p,ok1.p};
    identifier r1.i;
    @@
    i@p

    @depends on !bad disable optional_qualifier@
    identifier r1.i;
    @@
    +const
    struct rproc_ops i;

  • bb6869b21   remoteproc: st_slim_rproc: add a slimcore rproc driver ... Browse Code »

    slim core is used as a basis for many IPs in the STi
    chipsets such as fdma and demux. To avoid duplicating
    the elf loading code in each device driver a slim
    rproc driver has been created.

    This driver is designed to be used by other device drivers
    such as fdma, or demux whose IP is based around a slim core.
    The device driver can call slim_rproc_alloc() to allocate
    a slim rproc and slim_rproc_put() when finished.

    This driver takes care of ioremapping the slim
    registers (dmem, imem, slimcore, peripherals), whose offsets
    and sizes can change between IP's. It also obtains and enables
    any clocks used by the device. This approach avoids having
    a double mapping of the registers as slim_rproc does not register
    its own platform device. It also maps well to device tree
    abstraction as it allows us to have one dt node for the whole
    device.

    All of the generic rproc elf loading code can be reused, and
    we provide start() stop() hooks to start and stop the slim
    core once the firmware has been loaded. This has been tested
    successfully with fdma driver.
