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

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.
