config VIDEO
bool "Enable legacy video support"
depends on !DM_VIDEO
out On-screen Display (OSD) used on gdsys FPGAs to control dynamic
textual overlays of the display outputs.
+config SPLASH_SCREEN
+ bool "Show a splash-screen image"
+ help
+ If this option is set, the environment is checked for a variable
+ "splashimage". If found, the usual display of logo, copyright and
+ system information on the LCD is suppressed and the BMP image at the
+ address specified in "splashimage" is loaded instead. The console is
+ redirected to the "nulldev", too. This allows for a "silent" boot
+ where a splash screen is loaded very quickly after power-on.
+
+ The splash_screen_prepare() function is a weak function defined in
+ common/splash.c. It is called as part of the splash screen display
+ sequence. It gives the board an opportunity to prepare the splash
+ image data before it is processed and sent to the frame buffer by
+ U-Boot. Define your own version to use this feature.
+
+config SPLASHIMAGE_GUARD
+ bool "Support unaligned BMP images"
+ depends on SPLASH_SCREEN
+ help
+ If this option is set, then U-Boot will prevent the environment
+ variable "splashimage" from being set to a problematic address
+ (see doc/README.displaying-bmps).
+
+ This option is useful for targets where, due to alignment
+ restrictions, an improperly aligned BMP image will cause a data
+ abort. If you think you will not have problems with unaligned
+ accesses (for example because your toolchain prevents them)
+ there is no need to set this option.
+
+config SPLASH_SCREEN_ALIGN
+ bool "Allow positioning the splash image anywhere on the display"
+ depends on SPLASH_SCREEN || CMD_BMP
+ help
+ If this option is set the splash image can be freely positioned
+ on the screen. Environment variable "splashpos" specifies the
+ position as "x,y". If a positive number is given it is used as
+ number of pixel from left/top. If a negative number is given it
+ is used as number of pixel from right/bottom. You can also
+ specify 'm' for centering the image.
+
+ Example:
+ setenv splashpos m,m
+ => image at center of screen
+
+ setenv splashpos 30,20
+ => image at x = 30 and y = 20
+
+ setenv splashpos -10,m
+ => vertically centered image
+ at x = dspWidth - bmpWidth - 9
+
+config SPLASH_SOURCE
+ bool "Control the source of the splash image"
+ depends on SPLASH_SCREEN
+ help
+ Use the splash_source.c library. This library provides facilities to
+ declare board specific splash image locations, routines for loading
+ splash image from supported locations, and a way of controlling the
+ selected splash location using the "splashsource" environment
+ variable.
+
+ This CONFIG works as follows:
+
+ - If splashsource is set to a supported location name as defined by
+ board code, use that splash location.
+ - If splashsource is undefined, use the first splash location as
+ default.
+ - If splashsource is set to an unsupported value, do not load a splash
+ screen.
+
+ A splash source location can describe either storage with raw data, a
+ storage formatted with a file system or a FIT image. In case of a
+ filesystem, the splash screen data is loaded as a file. The name of
+ the splash screen file can be controlled with the environment variable
+ "splashfile".
+
+ To enable loading the splash image from a FIT image, CONFIG_FIT must
+ be enabled. The FIT image has to start at the 'offset' field address
+ in the selected splash location. The name of splash image within the
+ FIT shall be specified by the environment variable "splashfile".
+
+ In case the environment variable "splashfile" is not defined the
+ default name 'splash.bmp' will be used.
+
