51	help
52	  Support drawing text on the frame buffer console so that it can be
53	  used as a console. Rotation is not supported by this driver (see
54	  CONFIG_CONSOLE_ROTATION for that). A built-in 8x16 font is used
55	  for the display.
56
57config CONSOLE_ROTATION
58	bool "Support rotated displays"
59	depends on DM_VIDEO
60	help
61	  Sometimes, for example if the display is mounted in portrait
62	  mode or even if it's mounted landscape but rotated by 180degree,
63	  we need to rotate our content of the display relative to the
64	  framebuffer, so that user can read the messages which are
65	  printed out. Enable this option to include a text driver which can
66	  support this. The rotation is set by the 'rot' parameter in
67	  struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180
68	  degrees, 3=270 degrees.

73	help
74	  TrueTrype fonts can provide outline-drawing capability rather than
75	  needing to provide a bitmap for each font and size that is needed.
76	  With this option you can adjust the text size and use a variety of
77	  fonts. Note that this is noticeably slower than with normal console.
78
79config CONSOLE_TRUETYPE_SIZE

82	default 18
83	help
84	  This sets the font size for the console. The size is measured in
85	  pixels and is the nominal height of a character. Note that fonts
86	  are commonly measured in 'points', being 1/72 inch (about 3.52mm).
87	  However that measurement depends on the size of your display and
88	  there is no standard display density. At present there is not a
89	  method to select the display's physical size, which would allow
90	  U-Boot to calculate the correct font size.

98	  This is a work-around for boards which have 'lcd' in their stdout
99	  environment variable, but have moved to use driver model for video.
100	  In this case the console will no-longer work. While it is possible
101	  to update the environment, the breakage may be confusing for users.

511	  When CONFIG_CFB_CONSOLE is defined, the video console is the
512	  default console. The serial console can be forced by setting the
513	  environment 'console=serial'.

515config CFB_CONSOLE_ANSI
516	bool "Support ANSI escape sequences"
517	depends on CFB_CONSOLE
518	help
519	  This allows the colour buffer frame buffer driver to support
520	  a limited number of ANSI escape sequences (cursor control,
521	  erase functions and limited graphics rendition control). Normal
522	  output from U-Boot will pass through this filter.

526	depends on CFB_CONSOLE
527	default y
528	help
529	  If enable the framebuffer device will be initialized as an
530	  output-only device. The Keyboard driver will not be set up. This
531	  may be used if you have no keyboard device, or more than one
532	  (USB Keyboard, AT Keyboard).

537	default y if CFB_CONSOLE
538	help
539	  This draws a cursor after the last character. No blinking is
540	  provided. This makes it possible to see the current cursor
541	  position when entering text on the console. It is recommended to
542	  enable this.

547	help
548	  Display additional board information strings that normally go to
549	  the serial port. When this option is enabled, a board-specific
550	  function video_get_info_str() is called to get the string for
551	  each line of the display. The function should return the string,
552	  which can be empty if there is nothing to display for that line.

558	help
559	  When the console need to be scrolled, this is the number of
560	  lines to scroll by. It defaults to 1. Increasing this makes the
561	  console jump but can help speed up operation when scrolling
562	  is slow.
