+config VIDEO
+ bool "Enable legacy video support"
+ depends on !DM_VIDEO
+ help
+ Define this for video support, without using driver model. Some
+ drivers use this because they are not yet converted to driver
+ model. Video drivers typically provide a colour text console and
+ cursor.
+
+config CFB_CONSOLE
+ bool "Enable colour frame buffer console"
+ depends on VIDEO
+ default y if VIDEO
+ help
+ Enables the colour frame buffer driver. This supports colour
+ output on a bitmap display from an in-memory frame buffer.
+ Several colour devices are supported along with various options to
+ adjust the supported features. The driver is implemented in
+ cfb_console.c
+
+ The following defines are needed (cf. smiLynxEM, i8042)
+ VIDEO_FB_LITTLE_ENDIAN graphic memory organisation
+ (default big endian)
+ VIDEO_HW_RECTFILL graphic chip supports
+ rectangle fill (cf. smiLynxEM)
+ VIDEO_HW_BITBLT graphic chip supports
+ bit-blit (cf. smiLynxEM)
+ VIDEO_VISIBLE_COLS visible pixel columns (cols=pitch)
+ VIDEO_VISIBLE_ROWS visible pixel rows
+ VIDEO_PIXEL_SIZE bytes per pixel
+ VIDEO_DATA_FORMAT graphic data format
+ (0-5, cf. cfb_console.c)
+ VIDEO_FB_ADRS framebuffer address
+ VIDEO_KBD_INIT_FCT keyboard int fct (i.e. rx51_kp_init())
+ VIDEO_TSTC_FCT test char fct (i.e. rx51_kp_tstc)
+ VIDEO_GETC_FCT get char fct (i.e. rx51_kp_getc)
+ CONFIG_VIDEO_LOGO display Linux logo in upper left corner
+ CONFIG_VIDEO_BMP_LOGO use bmp_logo.h instead of linux_logo.h
+ for logo. Requires CONFIG_VIDEO_LOGO
+ CONFIG_CONSOLE_EXTRA_INFO
+ additional board info beside
+ the logo
+ CONFIG_HIDE_LOGO_VERSION
+ do not display bootloader
+ version string
+
+ When CONFIG_CFB_CONSOLE is defined, the video console is the
+ default console. The serial console can be forced by setting the
+ environment 'console=serial'.
+
+config CFB_CONSOLE_ANSI
+ bool "Support ANSI escape sequences"
+ depends on CFB_CONSOLE
+ help
+ This allows the colour buffer frame buffer driver to support
+ a limited number of ANSI escape sequences (cursor control,
+ erase functions and limited graphics rendition control). Normal
+ output from U-Boot will pass through this filter.
+
+config VGA_AS_SINGLE_DEVICE
+ bool "Set the video as an output-only device"
+ depends on CFB_CONSOLE
+ default y
+ help
+ If enable the framebuffer device will be initialized as an
+ output-only device. The Keyboard driver will not be set up. This
+ may be used if you have no keyboard device, or more than one
+ (USB Keyboard, AT Keyboard).
+
+config VIDEO_SW_CURSOR
+ bool "Enable a software cursor"
+ depends on CFB_CONSOLE
+ default y if CFB_CONSOLE
+ help
+ This draws a cursor after the last character. No blinking is
+ provided. This makes it possible to see the current cursor
+ position when entering text on the console. It is recommended to
+ enable this.
+
+config CONSOLE_EXTRA_INFO
+ bool "Display additional board information"
+ depends on CFB_CONSOLE
+ help
+ Display additional board information strings that normally go to
+ the serial port. When this option is enabled, a board-specific
+ function video_get_info_str() is called to get the string for
+ each line of the display. The function should return the string,
+ which can be empty if there is nothing to display for that line.
+
+config CONSOLE_SCROLL_LINES
+ int "Number of lines to scroll the console by"
+ depends on CFB_CONSOLE || DM_VIDEO || LCD
+ default 1
+ help
+ When the console need to be scrolled, this is the number of
+ lines to scroll by. It defaults to 1. Increasing this makes the
+ console jump but can help speed up operation when scrolling
+ is slow.
+
+config SYS_CONSOLE_BG_COL
+ hex "Background colour"
+ depends on CFB_CONSOLE
+ default 0x00
+ help
+ Defines the background colour for the console. The value is from
+ 0x00 to 0xff and the meaning depends on the graphics card.
+ Typically, 0x00 means black and 0xff means white. Do not set
+ the background and foreground to the same colour or you will see
+ nothing.
+
+config SYS_CONSOLE_FG_COL
+ hex "Foreground colour"
+ depends on CFB_CONSOLE
+ default 0xa0
+ help
+ Defines the foreground colour for the console. The value is from
+ 0x00 to 0xff and the meaning depends on the graphics card.
+ Typically, 0x00 means black and 0xff means white. Do not set
+ the background and foreground to the same colour or you will see
+ nothing.
+
+config LCD
+ bool "Enable legacy LCD support"
+ help
+ Define this to enable LCD support (for output to LCD display).
+ You will also need to select an LCD driver using an additional
+ CONFIG option. See the README for details. Drives which have been
+ converted to driver model will instead used CONFIG_DM_VIDEO.
+
+config VIDEO_DW_HDMI
+ bool
+ help
+ Enables the common driver code for the Designware HDMI TX
+ block found in SoCs from various vendors.
+ As this does not provide any functionality by itself (but
+ rather requires a SoC-specific glue driver to call it), it
+ can not be enabled from the configuration menu.
+
+config VIDEO_DSI_HOST_SANDBOX
+ bool "Enable sandbox for dsi host"
+ depends on SANDBOX
+ select VIDEO_MIPI_DSI
+ help
+ Enable support for sandbox dsi host device used for testing
+ purposes.
+ Display Serial Interface (DSI) defines a serial bus and
+ a communication protocol between the host and the device
+ (panel, bridge).
+
+config VIDEO_DW_MIPI_DSI
+ bool
+ select VIDEO_MIPI_DSI
+ help
+ Enables the common driver code for the Synopsis Designware
+ MIPI DSI block found in SoCs from various vendors.
+ As this does not provide any functionality by itself (but
+ rather requires a SoC-specific glue driver to call it), it
+ can not be enabled from the configuration menu.
+
+config VIDEO_SIMPLE
+ bool "Simple display driver for preconfigured display"
+ help
+ Enables a simple generic display driver which utilizes the
+ simple-framebuffer devicetree bindings.
+
+ This driver assumes that the display hardware has been initialized
+ before u-boot starts, and u-boot will simply render to the pre-
+ allocated frame buffer surface.
+
+config VIDEO_DT_SIMPLEFB
+ bool "Enable SimpleFB support for passing framebuffer to OS"
+ help
+ Enables the code to pass the framebuffer to the kernel as a
+ simple framebuffer in the device tree.
+ The video output is initialized by U-Boot, and kept by the
+ kernel.
+
+config OSD
+ bool "Enable OSD support"
+ depends on DM
+ default n
+ help
+ This supports drivers that provide a OSD (on-screen display), which
+ is a (usually text-oriented) graphics buffer to show information on
+ a display.
+
+config SANDBOX_OSD
+ bool "Enable sandbox OSD"
+ depends on OSD
+ help
+ Enable support for sandbox OSD device used for testing purposes.
+
+config IHS_VIDEO_OUT
+ bool "Enable IHS video out driver"
+ depends on OSD
+ help
+ Enable support for the gdsys Integrated Hardware Systems (IHS) video
+ out On-screen Display (OSD) used on gdsys FPGAs to control dynamic
+ textual overlays of the display outputs.
