+ * 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 CONFIG_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

+/************************************************************************
+ Get Parameters for the video mode:
+ The default video mode can be defined in CFG_DEFAULT_VIDEO_MODE.
+ If undefined, default video mode is set to 0x301
+ Parameters can be set via the variable "videomode" in the environment.
+ 2 diferent ways are possible:
+ "videomode=301" - 301 is a hexadecimal number describing the VESA
+ mode. Following modes are implemented:
+
+ Colors 640x480 800x600 1024x768 1152x864 1280x1024
+ --------+---------------------------------------------
+ 8 bits | 0x301 0x303 0x305 0x161 0x307
+ 15 bits | 0x310 0x313 0x316 0x162 0x319
+ 16 bits | 0x311 0x314 0x317 0x163 0x31A
+ 24 bits | 0x312 0x315 0x318 ? 0x31B
+ --------+---------------------------------------------
+ "videomode=bootargs"
+ - the parameters are parsed from the bootargs.
+ The format is "NAME:VALUE,NAME:VALUE" etc.
+ Ex.:
+ "bootargs=video=ctfb:x:800,y:600,depth:16,pclk:25000"
+ Parameters not included in the list will be taken from
+ the default mode, which is one of the following:
+ mode:0 640x480x24
+ mode:1 800x600x16
+ mode:2 1024x768x8
+ mode:3 960x720x24
+ mode:4 1152x864x16
+ mode:5 1280x1024x8
+
+ if "mode" is not provided within the parameter list,
+ mode:0 is assumed.
+ Following parameters are supported:
+ x xres = visible resolution horizontal
+ y yres = visible resolution vertical
+ pclk pixelclocks in pico sec
+ le left_marging time from sync to picture in pixelclocks
+ ri right_marging time from picture to sync in pixelclocks
+ up upper_margin time from sync to picture
+ lo lower_margin
+ hs hsync_len length of horizontal sync
+ vs vsync_len length of vertical sync
+ sync see FB_SYNC_*
+ vmode see FB_VMODE_*
+ depth Color depth in bits per pixel
+ All other parameters in the variable bootargs are ignored.
+ It is also possible to set the parameters direct in the
+ variable "videomode", or in another variable i.e.
+ "myvideo" and setting the variable "videomode=myvideo"..
