In this case 50 * no CONSOLE_EXTRA_INFO is possible. 51 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 52 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 53 * strings that normaly goes to serial 54 * port. This define requires a board 55 * specific function: 56 * video_drawstring (VIDEO_INFO_X, 57 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 58 * info); 59 * that fills a info buffer at i=row. 60 * s.a: board/eltec/bab7xx. 61 * 62 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 63 * character.
