  • 5a4675a91   cmd: fpga: Change return value to avoid printing usage text ... Browse Code »

    In cmd/fpga.c the commands should return enum command_ret_t, e.g.
    CMD_RET_USAGE, CMD_RET_SUCCESS, or CMD_RET_FAILURE. What they actually
    do is passing a return value from different 'fpga_' functions.

    Passing on a return value of -1 from a called function leads to printing
    out usage text. In case of actually correct usage with correctly
    specified parameters but some fail at runtime printing out that usage
    text is distracting.

    The reason is most 'fpga_' functions return either FPGA_SUCCESS or
    FPGA_FAIL, the latter was equal to -1 which is the same value as
    CMD_RET_USAGE. So just passing on FPGA_FAIL lead to printing out usage.

    We should only return CMD_RET_USAGE in cases, where the user sent wrong
    input. Every other case should return CMD_RET_SUCCESS or
    CMD_RET_FAILURE, and not simply pass an error code.

    Simply changing FPGA_FAIL from -1 to 1 gets the job done.

  • cedd48e2c   cmd: fpga: Add support to load secure bitstreams ... Browse Code »

    This patch adds support to load secure bitstreams(authenticated or
    encrypted or both). As of now, this feature is added and tested only
    for xilinx bitstreams and the secure bitstream was generated using
    xilinx bootgen tool, but the command is defined in more generic way.

    Command example to load authenticated and device key
    encrypted bitstream is as follows
    "fpga loads 0 100000 2000000 0 1"

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • 8b93a92f6   fpga: allow programming fpga from FIT image for all FPGA drivers ... Browse Code »

    This drops the limit that fpga is only loaded from FIT images for Xilinx.
    This is done by moving the 'partial' check from 'common/image.c' to
    'drivers/fpga/xilinx.c' (the only driver supporting partial images yet)
    and supplies a weak default implementation in 'drivers/fpga/fpga.c'.

  • 472d54605   Consolidate bool type ... Browse Code »

    'bool' is defined in random places. This patch consolidates them into a
    single header file include/linux/types.h, using stdbool.h introduced in C99.

    All other #define, typedef and enum are removed. They are all consistent with
    true = 1, false = 0.

    Replace FALSE, False with false. Replace TRUE, True with true.
    Skip *.py, *.php, lib/* files.

    Fix compiler warning:

    cmd_fpga.c:318: warning: passing argument 3 of 'fit_image_get_data'
    from incompatible pointer type

    Adding the needed 'const' here entails a whole bunch of additonal
    changes all over the FPGA code.

  • 3b8ac464f   FPGA: add support for downloading Lattice bitstream ... Browse Code »

    The patch adds support to load a Lattice's bitstream
    image (called VME file) into a Lattice FPGA. The code
    containing the state machine delivered as part of
    Lattice's ispVMtools is integrated.

    The FPGA is programmed using the JTAG interface. The
    board maintainer must provide accessors to drive the
    JTAG signals TCK, TMS, TDI and to get the value of the
    input signal TDO.

    This commit gets rid of a huge amount of silly white-space issues.
    Especially, all sequences of SPACEs followed by TAB characters get
    removed (unless they appear in print statements).

    Also remove all embedded "vim:" and "vi:" statements which hide
    indentation problems.
