  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 a keyboard interface for character input
  19  * but this is deprecated. Only rk51 uses it.
  20  *
  21  * Character output goes to a memory-mapped video
  22  * framebuffer with little or big-endian organisation.
  23  * With environment setting 'console=serial' the console i/o can be
  24  * forced to serial port.
  25  *
  26  * The driver uses graphic specific defines/parameters/functions:
  27  *
  28  * (for SMI LynxE graphic chip)
  29  *
  30  * VIDEO_FB_LITTLE_ENDIAN     - framebuffer organisation default: big endian
  31  * VIDEO_HW_RECTFILL          - graphic driver supports hardware rectangle fill
  32  * VIDEO_HW_BITBLT            - graphic driver supports hardware bit blt
  33  *
  34  * Console Parameters are set by graphic drivers global struct:
  35  *
  36  * VIDEO_VISIBLE_COLS         - x resolution
  37  * VIDEO_VISIBLE_ROWS         - y resolution
  38  * VIDEO_PIXEL_SIZE           - storage size in byte per pixel
  39  * VIDEO_DATA_FORMAT          - graphical data format GDF
  40  * VIDEO_FB_ADRS              - start of video memory
  41  *
  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_VIDEO_LOGO          - display Linux Logo in upper left corner.
  47  *                              Use CONFIG_SPLASH_SCREEN_ALIGN with
  48  *                              environment variable "splashpos" to place
  49  *                              the logo on other position. 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. No blinking is provided.
  64  *                              Uses the macros CURSOR_SET and
  65  *                              CURSOR_OFF.
