- * cfb_console.c
- *
- * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
- *
- * At the moment only the 8x16 font is tested and the font fore- and
- * background color is limited to black/white/gray colors. The Linux
- * logo can be placed in the upper left corner and additional board
- * information strings (that normally goes to serial port) can be drawn.
- *
- * The console driver can use a keyboard interface for character input
- * but this is deprecated. Only rk51 uses it.
- *
- * Character output goes to a memory-mapped video
- * framebuffer with little or big-endian organisation.
- * With environment setting 'console=serial' the console i/o can be
- * forced to serial port.
- *
- * The driver uses graphic specific defines/parameters/functions:
- *
- * (for SMI LynxE graphic chip)
- *
- * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian
- * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill
- * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt
- *
- * Console Parameters are set by graphic drivers global struct:
- *
- * VIDEO_VISIBLE_COLS - x resolution
- * VIDEO_VISIBLE_ROWS - y resolution
- * VIDEO_PIXEL_SIZE - storage size in byte per pixel
- * VIDEO_DATA_FORMAT - graphical data format GDF
- * VIDEO_FB_ADRS - start of video memory
- *
- * VIDEO_KBD_INIT_FCT - init function for keyboard
- * VIDEO_TSTC_FCT - keyboard_tstc function
- * VIDEO_GETC_FCT - keyboard_getc function
- *
- * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
- * CONFIG_CONSOLE_EXTRA_INFO - display additional board information
- * strings that normaly goes to serial
- * port. This define requires a board
- * specific function:
- * video_drawstring (VIDEO_INFO_X,
- * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
- * info);
- * that fills a info buffer at i=row.
- * s.a: board/eltec/bab7xx.
- *
- * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
- * character. No blinking is provided.
- * Uses the macros CURSOR_SET and
- * CURSOR_OFF.
