  10  * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
  11  *
  12  * At the moment only the 8x16 font is tested and the font fore- and
  13  * background color is limited to black/white/gray colors. 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. No blinking is provided.
  63  *                              Uses the macros CURSOR_SET and
  64  *                              CURSOR_OFF.
