When this option is enabled, a board-specific 631 function video_get_info_str() is called to get the string for 632 each line of the display. The function should return the string, 633 which can be empty if there is nothing to display for that line. 634 635config CONSOLE_SCROLL_LINES 636 int "Number of lines to scroll the console by" 637 depends on CFB_CONSOLE || DM_VIDEO || LCD 638 default 1 639 help 640 When the console need to be scrolled, this is the number of 641 lines to scroll by. It defaults to 1. Increasing this makes the 642 console jump but can help speed up operation when scrolling 643 is slow. 644 645config SYS_CONSOLE_BG_COL 646 hex "Background colour" 647 depends on CFB_CONSOLE 648 default 0x00 649 help 650 Defines the background colour for the console. The value is from 651 0x00 to 0xff and the meaning depends on the graphics card. 652 Typically, 0x00 means black and 0xff means white. Do not set 653 the background and foreground to the same colour or you will see 654 nothing. 655 656config SYS_CONSOLE_FG_COL 657 hex "Foreground colour" 658 depends on CFB_CONSOLE 659 default 0xa0 660 help 661 Defines the foreground colour for the console. The value is from 662 0x00 to 0xff and the meaning depends on the graphics card. 663 Typically, 0x00 means black and 0xff means white. Do not set 664 the background and foreground to the same colour or you will see 665 nothing. 666 667config LCD 668 bool "Enable legacy LCD support" 669 help 670 Define this to enable LCD support (for output to LCD display). 671 You will also need to select an LCD driver using an additional 672 CONFIG option. See the README for details. Drives which have been 673 converted to driver model will instead used CONFIG_DM_VIDEO. 674 675config VIDEO_DW_HDMI 676 bool 677 help 678 Enables the common driver code for the Designware HDMI TX 679 block found in SoCs from various vendors. 680 As this does not provide any functionality by itself (but 681 rather requires a SoC-specific glue driver to call it), it 682 can not be enabled from the configuration menu. 683 684config VIDEO_SIMPLE 685 bool "Simple display driver for preconfigured display" 686 help 687 Enables a simple generic display driver which utilizes the 688 simple-framebuffer devicetree bindings. 689 690 This driver assumes that the display hardware has been initialized 691 before u-boot starts, and u-boot will simply render to the pre- 692 allocated frame buffer surface. 693 694config VIDEO_DT_SIMPLEFB 695 bool "Enable SimpleFB support for passing framebuffer to OS" 696 help 697 Enables the code to pass the framebuffer to the kernel as a 698 simple framebuffer in the device tree. 699 The video output is initialized by U-Boot, and kept by the 700 kernel. 701 702config OSD 703 bool "Enable OSD support" 704 depends on DM 705 default n 706 help 707 This supports drivers that provide a OSD (on-screen display), which 708 is a (usually text-oriented) graphics buffer to show information on 709 a display. 710 711config SANDBOX_OSD 712 bool "Enable sandbox OSD" 713 depends on OSD 714 help 715 Enable support for sandbox OSD device used for testing purposes. 716 717config IHS_VIDEO_OUT 718 bool "Enable IHS video out driver" 719 depends on OSD 720 help 721 Enable support for the gdsys Integrated Hardware Systems (IHS) video 722 out On-screen Display (OSD) used on gdsys FPGAs to control dynamic 723 textual overlays of the display outputs. 724 725endmenu 726
