LED display internal API
=======================================
This README describes the LED display API.
The API is defined by the include file include/led-display.h
The first step in to define CONFIG_CMD_DISPLAY in the board config file.
Then you need to provide the following functions to access LED display:
void display_set(int cmd);
This function should control the state of the LED display. Argument is
an ORed combination of the following values:
DISPLAY_CLEAR -- clear the display
DISPLAY_HOME -- set the position to the beginning of display
int display_putc(char c);
This function should display it's parameter on the LED display in the
current position. Returns the displayed character on success or -1 in
case of failure.
With this functions defined 'display' command will display it's
arguments on the LED display (or clear the display if called without
arguments).
