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

U-Boot to calculate the correct font size.
