The Linux 14 * logo can be placed in the upper left corner and additional board 15 * information strings (that normally goes to serial port) can be drawn. 16 * 17 * The console driver can use a keyboard interface for character input 18 * but this is deprecated. Only rk51 uses it. 19 * 20 * Character output goes to a memory-mapped video 21 * framebuffer with little or big-endian organisation. 22 * With environment setting 'console=serial' the console i/o can be 23 * forced to serial port. 24 * 25 * The driver uses graphic specific defines/parameters/functions: 26 * 27 * (for SMI LynxE graphic chip) 28 * 29 * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian 30 * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill 31 * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt 32 * 33 * Console Parameters are set by graphic drivers global struct: 34 * 35 * VIDEO_VISIBLE_COLS - x resolution 36 * VIDEO_VISIBLE_ROWS - y resolution 37 * VIDEO_PIXEL_SIZE - storage size in byte per pixel 38 * VIDEO_DATA_FORMAT - graphical data format GDF 39 * VIDEO_FB_ADRS - start of video memory 40 * 41 * VIDEO_KBD_INIT_FCT - init function for keyboard 42 * VIDEO_TSTC_FCT - keyboard_tstc function 43 * VIDEO_GETC_FCT - keyboard_getc function 44 * 45 * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner. 46 * Use CONFIG_SPLASH_SCREEN_ALIGN with 47 * environment variable "splashpos" to place 48 * the logo on other position. In this case 49 * no CONSOLE_EXTRA_INFO is possible. 50 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 51 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 52 * strings that normaly goes to serial 53 * port. This define requires a board 54 * specific function: 55 * video_drawstring (VIDEO_INFO_X, 56 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 57 * info); 58 * that fills a info buffer at i=row. 59 * s.a: board/eltec/bab7xx. 60 * 61 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 62 * character.
