/*
 * 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 normaly goes to serial port) can be drawed.
 *
 * The console driver can use the standard PC keyboard interface (i8042)
 * for character input. 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)

 CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
 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

 CONFIG_I8042_KBD	     - AT Keyboard driver for i8042
 VIDEO_KBD_INIT_FCT	     - init function for keyboard
 VIDEO_TSTC_FCT		     - keyboard_tstc function
 VIDEO_GETC_FCT		     - keyboard_getc function

 CONFIG_CONSOLE_CURSOR	     - on/off drawing cursor is done with delay
			       loop in VIDEO_TSTC_FCT (i8042)
 CFG_CONSOLE_BLINK_COUNT     - value for delay loop - blink rate
 CONFIG_CONSOLE_TIME	     - display time/date in upper right corner,
			       needs CFG_CMD_DATE and CONFIG_CONSOLE_CURSOR
 CONFIG_VIDEO_LOGO	     - display Linux Logo in upper left corner
 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 initialised
			       as an output only device. The Keyboard driver
			       will not be set-up. This may be used, if you
			       have none 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
