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.
