2015-01-10lcd: refactor lcd console stuff into its own fileNikita Kiryanov
common/lcd.c is a mix of code portions that do different but related things. To improve modularity, the various code portions should be split into their own modules. Separate lcd console code into its own file.

2015-01-10lcd: make lcd_drawchars() independant of lcd_baseNikita Kiryanov
lcd_logo() has the following return value: #if defined(CONFIG_LCD_LOGO) && !defined(CONFIG_LCD_INFO_BELOW_LOGO) return (void *)((ulong)lcd_base + BMP_LOGO_HEIGHT * lcd_line_length); #else return (void *)lcd_base; #endif This return value gets assigned to lcd_console_address. lcd_console_address is not assigned or modified anywhere else. Thus: #if defined(CONFIG_LCD_LOGO) && !defined(CONFIG_LCD_INFO_BELOW_LOGO): y' = BMP_LOGO_HEIGHT + y; lcd_base + y' * lcd_line_length == lcd_base + (BMP_LOGO_HEIGHT + y) * lcd_line_length == lcd_base + BMP_LOGO_HEIGHT * lcd_line_length + y * lcd_line_length == lcd_console_address + y * lcd_line_length #else lcd_base + y * lcd_line_length == lcd_console_address + y * lcd_line_length #endif This is a preparatory step for extracting lcd console code into its own file.

Many of references of those macros must be fixed to suppress warnings.

2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>

2013-06-05lcd: add functions to set up simplefb device treeStephen Warren
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).

2013-03-20lcd: calculate line_length after lcd_ctrl_init()Stephen Warren
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.

2013-03-08lcd: add option for board specific splash screen preparationNikita Kiryanov
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.
