  • cefa47171   lcd: allow overriding lcd_get_size() ... Browse Code »

    Remove the redundant lcd_line_length initialisation which
    sneaked in when an earlier version of the patch of commit
    6d330719 has been rebased.

    Some lcd drivers need to setup lcd_line_length not from the
    panel_info parameters but by different means. Make the
    lcd_get_size() weak to allow setting lcd_line_length in
    a driver specific way.

    This patch moves all the font configuration values into video_font_data.h
    so they are all in the right place with the font. The video_font.h now only
    includes video_font_data.h and will allow us to select and include different
    font once more fonts are added.

  • 6a195d2d8   lcd: add functions to set up simplefb device tree ... Browse Code »

    simple-framebuffer is a new device tree binding that describes a pre-
    configured frame-buffer memory region and its format. The Linux kernel
    contains a driver that supports this binding. Implement functions to
    create a DT node (or fill in an existing node) with parameters that
    describe the framebuffer format that U-Boot is using.

    This will be immediately used by the Raspberry Pi board in U-Boot, and
    likely will be used by the Samsung ARM ChromeBook support soon too. It
    could well be used by many other boards (e.g. Tegra boards with built-in
    LCD panels, which aren't yet supported by the Linux kernel).

    Get rid of the global variables, and use the getter function where
    needed (so far no setter calls are needed).

  • 6d3307195   lcd: calculate line_length after lcd_ctrl_init() ... Browse Code »

    When an LCD driver is actually driving a regular external display, e.g.
    an HDMI monitor, the display resolution might not be known until the
    display controller has initialized, i.e. during lcd_ctrl_init(). However,
    lcd.c calculates lcd_line_length before calling this function, thus
    relying on a hard-coded resolution in struct panel_info.

    Instead, defer this calculation until after lcd_ctrl_init() has had the
    chance to dynamically determine the resolution. This needs to happen
    before lcd_clear(), since the value is used there.

    grep indicates that no code outside lcd.c uses this lcd_line_length; in
    particular, no lcd_ctrl_init() implementations read it.

  • 581bb4198   lcd: add option for board specific splash screen preparation ... Browse Code »

    Currently there is no logical place to put the code that prepares the
    splash image data. The splash image data should be ready in memory
    before bmp_display() is called, and after the environment is ready
    (since lcd.c looks for the splash image in an address specified by
    the environment variable "splashimage").

    Our window of opportunity in board_init_r() is therefore: between
    env_relocate() and bmp_display(), and from the available options
    only the lcd related functions in drv_lcd_init() seem appropriate
    for such lcd oriented code.

    Add the option to prepare the splash image data in lcd_logo() right
    before it is sent to be displayed.

    Commit fb6a9aab7ae78c (LCD: display 32bpp decompressed bitmap image)
    broke the check that allowed U-Boot to display 8 bpp BMPs on a 16
    bpp LCD screen, effectively turning this feature off.

    Restore this feature by changing the check back to the same meaning
    it originally had.
    To avoid future confusion, the check has also been rephrased to make
    its meaning clear.

    If the bmp pointer is null then U-Boot will get stuck when trying
    to load the image.
    What's worse, it will get stuck before the U-Boot shell becomes
    available to the user, thus making it difficult to correct the
    situation.

    To protect from the above scenario, check if the pointer is valid.

  • d3983ee85   font: split font data from video_font.h ... Browse Code »

    While video_font.h is useful even without referencing the font data, it
    is not possible to be included multiple times because it defines font
    data array right in the header.

    This patch splits the font data array into video_font_data.h and so now
    video_font.h can be included multiple times. This at least solves the
    code duplication in board/mcc200/lcd.c.
