11	  This enables driver model for LCD and video devices. These support
12	  a bitmap display of various sizes and depths which can be drawn on
13	  to display a command-line console or splash screen. Enabling this

84	  for the display.
85
86config CONSOLE_ROTATION
87	bool "Support rotated displays"
88	depends on DM_VIDEO
89	help
90	  Sometimes, for example if the display is mounted in portrait
91	  mode or even if it's mounted landscape but rotated by 180degree,
92	  we need to rotate our content of the display relative to the
93	  framebuffer, so that user can read the messages which are
94	  printed out. Enable this option to include a text driver which can
95	  support this. The rotation is set by the 'rot' parameter in
96	  struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180

103	  TrueTrype fonts can provide outline-drawing capability rather than
104	  needing to provide a bitmap for each font and size that is needed.
105	  With this option you can adjust the text size and use a variety of
106	  fonts. Note that this is noticeably slower than with normal console.
107
108config CONSOLE_TRUETYPE_SIZE
109	int "TrueType font size"

111	default 18
112	help
113	  This sets the font size for the console. The size is measured in
114	  pixels and is the nominal height of a character. Note that fonts
115	  are commonly measured in 'points', being 1/72 inch (about 3.52mm).
116	  However that measurement depends on the size of your display and
117	  there is no standard display density. At present there is not a
118	  method to select the display's physical size, which would allow
119	  U-Boot to calculate the correct font size.

125	 Normally the display is black on a white background, Enable this
126	 option to invert this, i.e. white on a black background. This can be
127	 better in low-light situations or to reduce eye strain in some
128	 cases.

130config NO_FB_CLEAR
131	bool "Skip framebuffer clear"
132	help
133	  If firmware (whatever loads u-boot) has already put a splash image
134	  on screen, you might want to preserve it until whatever u-boot
135	  loads takes over the screen.  This, for example, can be used to
136	  keep splash image on screen until grub graphical boot menu starts.

140config VIDCONSOLE_AS_LCD
141	bool "Use 'vidconsole' when 'lcd' is seen in stdout"
142	depends on DM_VIDEO
143	help
144	  This is a work-around for boards which have 'lcd' in their stdout
145	  environment variable, but have moved to use driver model for video.
146	  In this case the console will no-longer work. While it is possible
147	  to update the environment, the breakage may be confusing for users.
148	  This option will be removed around the end of 2016.

167
168config VIDEO_VESA
169	bool "Enable VESA video driver support"
170	default n
171	help
172	  Turn on this option to enable a very simple driver which uses vesa
173	  to discover the video mode and then provides a frame buffer for use
174	  by U-Boot. This can in principle be used with any platform that
175	  supports PCI and video cards that support VESA BIOS Extension (VBE).
