26  *
27  * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
28  *
29  * At the moment only the 8x16 font is tested and the font fore- and
30  * background color is limited to black/white/gray colors. The Linux
31  * logo can be placed in the upper left corner and additional board
32  * information strings (that normaly goes to serial port) can be drawed.
33  *
34  * The console driver can use the standard PC keyboard interface (i8042)
35  * for character input. Character output goes to a memory mapped video
36  * framebuffer with little or big-endian organisation.
37  * With environment setting 'console=serial' the console i/o can be
38  * forced to serial port.
39 
40  The driver uses graphic specific defines/parameters/functions:
41 
42  (for SMI LynxE graphic chip)
43 
44  CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
45  VIDEO_FB_LITTLE_ENDIAN	 - framebuffer organisation default: big endian
46  VIDEO_HW_RECTFILL	 - graphic driver supports hardware rectangle fill
47  VIDEO_HW_BITBLT	 - graphic driver supports hardware bit blt
48 
49  Console Parameters are set by graphic drivers global struct:
50 
51  VIDEO_VISIBLE_COLS	     - x resolution
52  VIDEO_VISIBLE_ROWS	     - y resolution
53  VIDEO_PIXEL_SIZE	     - storage size in byte per pixel
54  VIDEO_DATA_FORMAT	     - graphical data format GDF
55  VIDEO_FB_ADRS		     - start of video memory
56 
57  CONFIG_I8042_KBD	     - AT Keyboard driver for i8042
58  VIDEO_KBD_INIT_FCT	     - init function for keyboard
59  VIDEO_TSTC_FCT		     - keyboard_tstc function
60  VIDEO_GETC_FCT		     - keyboard_getc function
61 
62  CONFIG_CONSOLE_CURSOR	     - on/off drawing cursor is done with delay
63 			       loop in VIDEO_TSTC_FCT (i8042)
64  CONFIG_SYS_CONSOLE_BLINK_COUNT     - value for delay loop - blink rate
65  CONFIG_CONSOLE_TIME	     - display time/date in upper right corner,
66 			       needs CONFIG_CMD_DATE and CONFIG_CONSOLE_CURSOR
67  CONFIG_VIDEO_LOGO	     - display Linux Logo in upper left corner
68  CONFIG_VIDEO_BMP_LOGO	     - use bmp_logo instead of linux_logo
69  CONFIG_CONSOLE_EXTRA_INFO   - display additional board information strings
70 			       that normaly goes to serial port. This define
71 			       requires a board specific function:
72 			       video_drawstring (VIDEO_INFO_X,
73 						 VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
74 						 info);
75 			       that fills a info buffer at i=row.
76 			       s.a: board/eltec/bab7xx.
77 CONFIG_VGA_AS_SINGLE_DEVICE  - If set the framebuffer device will be initialised
78 			       as an output only device. The Keyboard driver
79 			       will not be set-up. This may be used, if you
80 			       have none or more than one Keyboard devices
81 			       (USB Keyboard, AT Keyboard).
82 
83 CONFIG_VIDEO_SW_CURSOR:	     - Draws a cursor after the last character. No
84 			       blinking is provided. Uses the macros CURSOR_SET
85 			       and CURSOR_OFF.
86 CONFIG_VIDEO_HW_CURSOR:	     - Uses the hardware cursor capability of the
87 			       graphic chip. Uses the macro CURSOR_SET.
88 			       ATTENTION: If booting an OS, the display driver
89 			       must disable the hardware register of the graphic
90 			       chip. Otherwise a blinking field is displayed
