122 pixels and is the nominal height of a character. Note that fonts
123 are commonly measured in 'points', being 1/72 inch (about 3.52mm).
124 However that measurement depends on the size of your display and
125 there is no standard display density. At present there is not a
126 method to select the display's physical size, which would allow
127 U-Boot to calculate the correct font size.

422 This is one of the SPI communication pins, involved in setting up a
423 working LCD configuration. The exact role of SPI may differ for
424 different hardware setups. If wired up, this pin may provide additional
425 useful functionality. Such as bi-directional communication with the
426 hardware and LCD panel id retrieval (if the panel can report it). The
427 option takes a string in the format understood by 'name_to_gpio'
428 function, e.g. PH1 for pin 1 of port H.
