  27  * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
  28  *
  29  * At the moment only the 8x16 font is tested and the font fore- and
  30  * background color is limited to black/white/gray colors. The Linux
  31  * logo can be placed in the upper left corner and additional board
  32  * information strings (that normaly goes to serial port) can be drawed.
  33  *
  34  * The console driver can use the standard PC keyboard interface (i8042)
  35  * for character input. Character output goes to a memory mapped video
  36  * framebuffer with little or big-endian organisation.
  37  * With environment setting 'console=serial' the console i/o can be
  38  * forced to serial port.
  39
  40  The driver uses graphic specific defines/parameters/functions:
  41
  42  (for SMI LynxE graphic chip)
  43
  44  CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
  45  VIDEO_FB_LITTLE_ENDIAN  - framebuffer organisation default: big endian
  46  VIDEO_HW_RECTFILL       - graphic driver supports hardware rectangle fill
  47  VIDEO_HW_BITBLT         - graphic driver supports hardware bit blt
  48
  49  Console Parameters are set by graphic drivers global struct:
  50
  51  VIDEO_VISIBLE_COLS          - x resolution
  52  VIDEO_VISIBLE_ROWS          - y resolution
  53  VIDEO_PIXEL_SIZE            - storage size in byte per pixel
  54  VIDEO_DATA_FORMAT           - graphical data format GDF
  55  VIDEO_FB_ADRS               - start of video memory
  56
  57  CONFIG_I8042_KBD            - AT Keyboard driver for i8042
  58  VIDEO_KBD_INIT_FCT          - init function for keyboard
  59  VIDEO_TSTC_FCT              - keyboard_tstc function
  60  VIDEO_GETC_FCT              - keyboard_getc function
  61
  62  CONFIG_CONSOLE_CURSOR       - on/off drawing cursor is done with delay
  63                                loop in VIDEO_TSTC_FCT (i8042)
  64  CONFIG_SYS_CONSOLE_BLINK_COUNT     - value for delay loop - blink rate
  65  CONFIG_CONSOLE_TIME         - display time/date in upper right corner,
  66                                needs CONFIG_CMD_DATE and CONFIG_CONSOLE_CURSOR
  67  CONFIG_VIDEO_LOGO           - display Linux Logo in upper left corner
  68  CONFIG_VIDEO_BMP_LOGO       - use bmp_logo instead of linux_logo
  69  CONFIG_CONSOLE_EXTRA_INFO   - display additional board information strings
  70                                that normaly goes to serial port. This define
  71                                requires a board specific function:
  72                                video_drawstring (VIDEO_INFO_X,
  73                                                  VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
  74                                                  info);
  75                                that fills a info buffer at i=row.
  76                                s.a: board/eltec/bab7xx.
  77 CONFIG_VGA_AS_SINGLE_DEVICE  - If set the framebuffer device will be initialised
  78                                as an output only device. The Keyboard driver
  79                                will not be set-up. This may be used, if you
  80                                have none or more than one Keyboard devices
  81                                (USB Keyboard, AT Keyboard).
  82
  83 CONFIG_VIDEO_SW_CURSOR:      - Draws a cursor after the last character. No
  84                                blinking is provided. Uses the macros CURSOR_SET
  85                                and CURSOR_OFF.
  86 CONFIG_VIDEO_HW_CURSOR:      - Uses the hardware cursor capability of the
  87                                graphic chip. Uses the macro CURSOR_SET.
  88                                ATTENTION: If booting an OS, the display driver
  89                                must disable the hardware register of the graphic
  90                                chip. Otherwise a blinking field is displayed
