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.
