    5

    Let's use the i.MX common miscellaneous reset API
    to reset the LCDIF block so that we may eliminate
    a random hang issue at the arch_preboot_os() stage
    when we disable the LCDIF. This patch also waits
    for a VSYNC interrupt to guarantee the reset is
    done at the VSYNC edge, which somehow makes the
    LCDIF consume the display FIFO(?) and helps the
    LCDIF work normally at the kernel stage.

  • cec21a6fe   ENGR00321146 gis: faster auto standards detection ... Browse Code »

    Vadc need long time to auto standards detection,
    the default standard is NTSC, if vadc connect to PAL
    camera and no enough time to detect the video mode,
    driver will get wrong standard.

    Confirmation from chip design architecture that auto detect function
    is not required by rear-view camera application.

    Setting register vdec_stddbg standard_filte bits to 0
    makes the standard detection faster, the issue duplicate
    decrease to 1%.

  • b8ab9b3ea   ENGR00315499-7 Add EPDC splash screen for MX 6DL SabreSD and 6SL EVK ... Browse Code »
    5

    Add EPDC splash screen feature for MX6SL EVK, and MX6DL SABRESD board.

    - Currently, splash screen consists of a simple black border
    around a white screen. Done this way to save in memory footprint.

    - EPDC splash screen is disabled by default in the config file for MX6DL_SABRESD
    and MX6SL_EVK. If left enabled, the U-Boot image will not boot correctly
    (hang), since some additional content on the boot device (waveform file) is
    required for EPDC splash to work correctly.

    Please refer to Linux Reference Manual for how to flash WAVEFORM file.

  • 7d95f2a32   sandbox: Add LCD driver ... Browse Code »

    Add a simple LCD driver which uses SDL to display the image. We update the
    image regularly, while still providing for reasonable performance.

    Adjust the common lcd code to support sandbox.

    For command-line runs we do not want the LCD to be displayed, so add a
    --show_lcd option to enable it.

  • 5ca05c8b0   cfb_console: align fields in gzipped .bmp files ... Browse Code »

    .bmp files contain 32-bit integers aligned at offsets of +2, +6,
    et cetera within the bmp_header structure (see include/bmp_layout.h).

    Support for gzip-compressed .bmp files is present in the cfb_console
    display subsystem by uncompressing them prior to use.

    This patch forces the in-memory header to be aligned properly
    for these compressed images by extracting them to a 2-byte
    offset in the memory returned by malloc. Since malloc will always
    return a 4-byte aligned value, this forces the .bmp header
    fields to be naturally aligned on 4-byte addresses.

    Refer to these files for more details:
    doc/README.displaying-bmps

    Depending on the firmware's video options [1] the active SDTV or
    HDTV mode can yield a framebuffer with noncontiguous horizontal lines,
    giving a messed up display, for both, u-boot and the loaded kernel.

    Fix this by setting lcd_line_length to the pitch value of the configured
    framebuffer.

  • 2740e5de4   video: ipu_disp: Fix clock polarity logic ... Browse Code »

    Currently the HDMI splash screen image quality on mx6solo does not show a
    very stable image.

    By comparing the IPU driver from U-boot with the one from FSL 4.1.0 BSP,
    we can see that there is an inverted logic for setting the DI_GEN_POL_CLK bit.

    >From FSL BSP [1] we have:

    if (!sig.clk_pol)
    di_gen |= DI_GEN_POLARITY_DISP_CLK;

    Applying the same logic into U-boot fixes the HDMI image stability.
