/*
 * 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_LOGO	      - display Linux Logo in upper left corner.
 *				Use CONFIG_SPLASH_SCREEN_ALIGN with
 *				environment variable "splashpos" to place
 *				the logo on other position. In this case
 *				no CONSOLE_EXTRA_INFO is possible.
 * 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_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
 *				initialized as an output only device.
 *				The Keyboard driver will not be
 *				set-up.  This may be used, if you have
 *				no or more than one Keyboard devices
 *				(USB Keyboard, AT Keyboard).
 *
 * CONFIG_VIDEO_SW_CURSOR:    - Draws a cursor after the last
 *				character. No blinking is provided.
 *				Uses the macros CURSOR_SET and
 *				CURSOR_OFF.
 *
 * CONFIG_VIDEO_HW_CURSOR:    - Uses the hardware cursor capability
 *				of the graphic chip. Uses the macro
 *				CURSOR_SET. ATTENTION: If booting an
 *				OS, the display driver must disable
 *				the hardware register of the graphic
 *				chip. Otherwise a blinking field is
 *				displayed.
