  11  * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
  12  *
  13  * At the moment only the 8x16 font is tested and the font fore- and
  14  * background color is limited to black/white/gray colors. The Linux
  15  * logo can be placed in the upper left corner and additional board
  16  * information strings (that normally goes to serial port) can be drawn.
  17  *
  18  * The console driver can use the standard PC keyboard interface (i8042)
  19  * for character input. Character output goes to a memory mapped video
  20  * framebuffer with little or big-endian organisation.
  21  * With environment setting 'console=serial' the console i/o can be
  22  * forced to serial port.
  23  *
  24  * The driver uses graphic specific defines/parameters/functions:
  25  *
  26  * (for SMI LynxE graphic chip)
  27  *
  28  * CONFIG_VIDEO_SMI_LYNXEM    - use graphic driver for SMI 710,712,810
  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  * CONFIG_I8042_KBD           - AT Keyboard driver for i8042
  42  * VIDEO_KBD_INIT_FCT         - init function for keyboard
  43  * VIDEO_TSTC_FCT             - keyboard_tstc function
  44  * VIDEO_GETC_FCT             - keyboard_getc function
  45  *
  46  * CONFIG_CONSOLE_CURSOR      - on/off drawing cursor is done with
  47  *                              delay loop in VIDEO_TSTC_FCT (i8042)
  48  *
  49  * CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
  50  * CONFIG_CONSOLE_TIME        - display time/date in upper right
  51  *                              corner, needs CONFIG_CMD_DATE and
  52  *                              CONFIG_CONSOLE_CURSOR
  53  * CONFIG_VIDEO_LOGO          - display Linux Logo in upper left corner.
  54  *                              Use CONFIG_SPLASH_SCREEN_ALIGN with
  55  *                              environment variable "splashpos" to place
  56  *                              the logo on other position. In this case
  57  *                              no CONSOLE_EXTRA_INFO is possible.
  58  * CONFIG_VIDEO_BMP_LOGO      - use bmp_logo instead of linux_logo
  59  * CONFIG_CONSOLE_EXTRA_INFO  - display additional board information
  60  *                              strings that normaly goes to serial
  61  *                              port.  This define requires a board
  62  *                              specific function:
  63  *                              video_drawstring (VIDEO_INFO_X,
  64  *                                      VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
  65  *                                      info);
  66  *                              that fills a info buffer at i=row.
  67  *                              s.a: board/eltec/bab7xx.
  68  * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
  69  *                              initialized as an output only device.
  70  *                              The Keyboard driver will not be
  71  *                              set-up.  This may be used, if you have
  72  *                              no or more than one Keyboard devices
  73  *                              (USB Keyboard, AT Keyboard).
  74  *
  75  * CONFIG_VIDEO_SW_CURSOR:    - Draws a cursor after the last
  76  *                              character. No blinking is provided.
  77  *                              Uses the macros CURSOR_SET and
  78  *                              CURSOR_OFF.
  79  *
  80  * CONFIG_VIDEO_HW_CURSOR:    - Uses the hardware cursor capability
  81  *                              of the graphic chip. Uses the macro
  82  *                              CURSOR_SET. ATTENTION: If booting an
  83  *                              OS, the display driver must disable
  84  *                              the hardware register of the graphic
  85  *                              chip. Otherwise a blinking field is
  86  *                              displayed.
