  • e29ff72b7   remoteproc: remove rproc_elf32_sanity_check ... Browse Code »

    Since checks are present in the remoteproc elf loader before calling
    da_to_va, loading a elf64 will work on 32bits flavors of kernel.
    Indeed, if a segment size is larger than what size_t can hold, the
    loader will return an error so the functionality is equivalent to
    what exists today.

  • 826c33909   remoteproc: Rename rproc_elf_sanity_check for elf32 ... Browse Code »

    Since this function will be modified to support both elf32 and elf64,
    rename the existing one to elf32 (which is the only supported format
    at the moment). This will allow not to introduce possible side effect
    when adding elf64 support (ie: all backends will still support only
    elf32 if not requested explicitely using rproc_elf_sanity_check).

  • e4ae4b7d0   remoteproc: Use u64 type for boot_addr ... Browse Code »

    elf64 entry is defined as a u64. Since boot_addr is used to store the
    elf entry point, change boot_addr type to u64 to support both elf32
    and elf64. In the same time, fix users that were using this variable.

  • 3df52ed7f   remoteproc: st: add reserved memory support ... Browse Code »

    ST remote processor needs some specified memory regions for
    firmware and IPC.
    Memory regions are defined as reserved memory and should
    be registered in remoteproc core thanks to rproc_add_carveout
    function before rproc_start. For this, st rproc driver implements
    prepare ops.

  • 1e13c7fb4   remoteproc: st: explicitly request exclusive reset control ... Browse Code »

    Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
    reset lines") started to transition the reset control request API calls
    to explicitly state whether the driver needs exclusive or shared reset
    control behavior. Convert all drivers requesting exclusive resets to the
    explicit API call so the temporary transition helpers can be removed.

    No functional changes.

  • 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
    after applying the changes.
