  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.

  98           This is a work-around for boards which have 'lcd' in their stdout
  99           environment variable, but have moved to use driver model for video.
 100           In this case the console will no-longer work. While it is possible
