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 normally goes to serial port) can be drawn.
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
63  *				delay loop in VIDEO_TSTC_FCT (i8042)
64  *
65  * CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
66  * CONFIG_CONSOLE_TIME	      - display time/date in upper right
67  *				corner, needs CONFIG_CMD_DATE and
68  *				CONFIG_CONSOLE_CURSOR
69  * CONFIG_VIDEO_LOGO	      - display Linux Logo in upper left corner.
70  *				Use CONFIG_SPLASH_SCREEN_ALIGN with
71  *				environment variable "splashpos" to place
72  *				the logo on other position. In this case
73  *				no CONSOLE_EXTRA_INFO is possible.
74  * CONFIG_VIDEO_BMP_LOGO      - use bmp_logo instead of linux_logo
75  * CONFIG_CONSOLE_EXTRA_INFO  - display additional board information
76  *				strings that normaly goes to serial
77  *				port.  This define requires a board
78  *				specific function:
79  *				video_drawstring (VIDEO_INFO_X,
80  *					VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
81  *					info);
82  *				that fills a info buffer at i=row.
83  *				s.a: board/eltec/bab7xx.
84  * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
85  *				initialized as an output only device.
86  *				The Keyboard driver will not be
87  *				set-up.  This may be used, if you have
88  *				no or more than one Keyboard devices
89  *				(USB Keyboard, AT Keyboard).
90  *
91  * CONFIG_VIDEO_SW_CURSOR:    - Draws a cursor after the last
92  *				character. No blinking is provided.
93  *				Uses the macros CURSOR_SET and
94  *				CURSOR_OFF.
95  *
96  * CONFIG_VIDEO_HW_CURSOR:    - Uses the hardware cursor capability
97  *				of the graphic chip. Uses the macro
98  *				CURSOR_SET. ATTENTION: If booting an
99  *				OS, the display driver must disable
100  *				the hardware register of the graphic
101  *				chip. Otherwise a blinking field is
102  *				displayed.
