pixels and is the nominal height of a character. Note that fonts

are commonly measured in 'points', being 1/72 inch (about 3.52mm).

there is no standard display density. At present there is not a

U-Boot to calculate the correct font size.

help
|
|
This enables support for integrated graphics on Intel ivybridge
|
|
devices. Initialisation is mostly performed by a VGA boot ROM, with
|
|
some setup handled by U-Boot itself. The graphics adaptor works as
|
|
a VESA device and supports LCD panels, eDP and LVDS outputs.
|
|
Configuration of most aspects of device operation is performed using
|
|
a special tool which configures the VGA ROM, but the graphics
|
|
resolution can be selected in U-Boot.
