The Linux * logo can be placed in the upper left corner and additional board * information strings (that normally goes to serial port) can be drawn. * * The console driver can use a keyboard interface for character input * but this is deprecated.

In this case * no CONSOLE_EXTRA_INFO is possible. * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo * CONFIG_CONSOLE_EXTRA_INFO - display additional board information * strings that normaly goes to serial * port. This define requires a board * specific function: * video_drawstring (VIDEO_INFO_X, * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, * info); * that fills a info buffer at i=row. * s.a: board/eltec/bab7xx. * * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last * character.
