  • 9ce3bf225   remoteproc: Use size_t type for len in da_to_va ... Browse Code »

    With upcoming changes in elf loader for elf64 support, section size will
    be a u64. When used with da_to_va, this will potentially lead to
    overflow if using the current "int" type for len argument. Change
    da_to_va prototype to use a size_t for len and fix all users of this
    function.

  • c008fad26   drivers: remoteproc: constify rproc_ops structures ... Browse Code »

    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;

    File size details:

    Size of the file remoteproc/da8xx_remoteproc.o remains the same before and

  • ddf711872   remoteproc: Introduce auto-boot flag ... Browse Code »

    Introduce an "auto-boot" flag on rprocs to make it possible to flag
    remote processors without vdevs to automatically boot once the firmware
    is found.

    Preserve previous behavior of the wkup_m3 processor being explicitly
    booted by a consumer.

  • a01bc0d5f   remoteproc/wkup_m3: add a remoteproc driver for TI Wakeup M3 ... Browse Code »

    Add a remoteproc driver to load the firmware and boot a small
    Wakeup M3 processor present on TI AM33xx and AM43xx SoCs. This
    Wakeup M3 remote processor is an integrated Cortex M3 that allows
    the SoC to enter the lowest possible power state by taking control
    from the MPU after it has gone into its own low power state and
    shutting off any additional peripherals.

    The Wakeup M3 processor has two internal memory regions - 16 kB of
    unified instruction memory called UMEM used to store executable
    code, and 8 kB of data memory called DMEM used for all data sections.
    The Wakeup M3 processor executes its code entirely from within the
    UMEM and uses the DMEM for any data. It does not use any external
    memory or any other external resources. The device address view has
    the UMEM at address 0x0 and DMEM at address 0x80000, and these are
    computed automatically within the driver based on relative address
    calculation from the corresponding device tree IOMEM resources.
    These device addresses are used to aid the core remoteproc ELF
    loader code to properly translate and load the firmware segments
    through the .rproc_da_to_va ops.
