| This enables driver model for LCD and video devices. These support |
| a bitmap display of various sizes and depths which can be drawn on |

| help |
| Support drawing text on the frame buffer console so that it can be |
| used as a console. Rotation is not supported by this driver (see |
| CONFIG_CONSOLE_ROTATION for that). A built-in 8x16 font is used |
| for the display. |
| |
| config CONSOLE_ROTATION |
| bool "Support rotated displays" |
| depends on DM_VIDEO |
| help |
| Sometimes, for example if the display is mounted in portrait |
| mode or even if it's mounted landscape but rotated by 180degree, |
| we need to rotate our content of the display relative to the |
| framebuffer, so that user can read the messages which are |
| printed out. Enable this option to include a text driver which can |
| support this. The rotation is set by the 'rot' parameter in |
| struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180 |
| degrees, 3=270 degrees. |
| |
| config CONSOLE_TRUETYPE |
| bool "Support a console that uses TrueType fonts" |
| depends on DM_VIDEO |
| help |
| TrueTrype fonts can provide outline-drawing capability rather than |
| needing to provide a bitmap for each font and size that is needed. |
| With this option you can adjust the text size and use a variety of |
| fonts. Note that this is noticeably slower than with normal console. |
| |
| config CONSOLE_TRUETYPE_SIZE |
| int "TrueType font size" |
| depends on CONSOLE_TRUETYPE |
| default 18 |
| help |
| This sets the font size for the console. The size is measured in |
| pixels and is the nominal height of a character. Note that fonts |
| are commonly measured in 'points', being 1/72 inch (about 3.52mm). |
| However that measurement depends on the size of your display and |
| there is no standard display density. At present there is not a |
| method to select the display's physical size, which would allow |
| U-Boot to calculate the correct font size. |

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

| config VIDEO_VESA |
| bool "Enable VESA video driver support" |

| help |
| Turn on this option to enable a very simple driver which uses vesa |
| to discover the video mode and then provides a frame buffer for use |
| by U-Boot. This can in principle be used with any platform that |
| supports PCI and video cards that support VESA BIOS Extension (VBE). |
