11  * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
12  *
13  * At the moment only the 8x16 font is tested and the font fore- and
14  * background color is limited to black/white/gray colors. The Linux
15  * logo can be placed in the upper left corner and additional board
16  * information strings (that normally goes to serial port) can be drawn.
17  *
18  * The console driver can use the standard PC keyboard interface (i8042)
19  * for character input. Character output goes to a memory mapped video
20  * framebuffer with little or big-endian organisation.
21  * With environment setting 'console=serial' the console i/o can be
22  * forced to serial port.
23  *
24  * The driver uses graphic specific defines/parameters/functions:
25  *
26  * (for SMI LynxE graphic chip)
27  *
28  * CONFIG_VIDEO_SMI_LYNXEM    - use graphic driver for SMI 710,712,810
29  * VIDEO_FB_LITTLE_ENDIAN     - framebuffer organisation default: big endian
30  * VIDEO_HW_RECTFILL	      - graphic driver supports hardware rectangle fill
31  * VIDEO_HW_BITBLT	      - graphic driver supports hardware bit blt
32  *
33  * Console Parameters are set by graphic drivers global struct:
34  *
35  * VIDEO_VISIBLE_COLS	      - x resolution
36  * VIDEO_VISIBLE_ROWS	      - y resolution
37  * VIDEO_PIXEL_SIZE	      - storage size in byte per pixel
38  * VIDEO_DATA_FORMAT	      - graphical data format GDF
39  * VIDEO_FB_ADRS	      - start of video memory
40  *
41  * CONFIG_I8042_KBD	      - AT Keyboard driver for i8042
42  * VIDEO_KBD_INIT_FCT	      - init function for keyboard
43  * VIDEO_TSTC_FCT	      - keyboard_tstc function
44  * VIDEO_GETC_FCT	      - keyboard_getc function
45  *
46  * CONFIG_CONSOLE_CURSOR      - on/off drawing cursor is done with
47  *				delay loop in VIDEO_TSTC_FCT (i8042)
48  *
49  * CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
50  * CONFIG_CONSOLE_TIME	      - display time/date in upper right
51  *				corner, needs CONFIG_CMD_DATE and
52  *				CONFIG_CONSOLE_CURSOR
53  * CONFIG_VIDEO_LOGO	      - display Linux Logo in upper left corner.
54  *				Use CONFIG_SPLASH_SCREEN_ALIGN with
55  *				environment variable "splashpos" to place
56  *				the logo on other position. In this case
57  *				no CONSOLE_EXTRA_INFO is possible.
58  * CONFIG_VIDEO_BMP_LOGO      - use bmp_logo instead of linux_logo
59  * CONFIG_CONSOLE_EXTRA_INFO  - display additional board information
60  *				strings that normaly goes to serial
61  *				port.  This define requires a board
62  *				specific function:
63  *				video_drawstring (VIDEO_INFO_X,
64  *					VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
65  *					info);
66  *				that fills a info buffer at i=row.
67  *				s.a: board/eltec/bab7xx.
68  * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
69  *				initialized as an output only device.
70  *				The Keyboard driver will not be
71  *				set-up.  This may be used, if you have
72  *				no or more than one Keyboard devices
73  *				(USB Keyboard, AT Keyboard).
74  *
75  * CONFIG_VIDEO_SW_CURSOR:    - Draws a cursor after the last
76  *				character. No blinking is provided.
77  *				Uses the macros CURSOR_SET and
78  *				CURSOR_OFF.
79  *
80  * CONFIG_VIDEO_HW_CURSOR:    - Uses the hardware cursor capability
81  *				of the graphic chip. Uses the macro
82  *				CURSOR_SET. ATTENTION: If booting an
83  *				OS, the display driver must disable
84  *				the hardware register of the graphic
85  *				chip. Otherwise a blinking field is
86  *				displayed.
