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  * CONFIG_VIDEO_BMP_LOGO      - use bmp_logo instead of linux_logo
71  * CONFIG_CONSOLE_EXTRA_INFO  - display additional board information
72  *                              strings that normaly goes to serial
73  *                              port.  This define requires a board
74  *                              specific function:
75  *                              video_drawstring (VIDEO_INFO_X,
76  *                                      VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
77  *                                      info);
78  *                              that fills a info buffer at i=row.
79  *                              s.a: board/eltec/bab7xx.
80  * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
81  *                              initialized as an output only device.
82  *                              The Keyboard driver will not be
83  *                              set-up.  This may be used, if you have
84  *                              no or more than one Keyboard devices
85  *                              (USB Keyboard, AT Keyboard).
86  *
87  * CONFIG_VIDEO_SW_CURSOR:    - Draws a cursor after the last
88  *                              character. No blinking is provided.
89  *                              Uses the macros CURSOR_SET and
90  *                              CURSOR_OFF.
91  *
92  * CONFIG_VIDEO_HW_CURSOR:    - Uses the hardware cursor capability
93  *                              of the graphic chip. Uses the macro
94  *                              CURSOR_SET. ATTENTION: If booting an
95  *                              OS, the display driver must disable
96  *                              the hardware register of the graphic
97  *                              chip. Otherwise a blinking field is
98  *                              displayed.
