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 a keyboard interface for character input
19  * but this is deprecated. Only rk51 uses it.
20  *
21  * Character output goes to a memory-mapped video
22  * framebuffer with little or big-endian organisation.
23  * With environment setting 'console=serial' the console i/o can be
24  * forced to serial port.
25  *
26  * The driver uses graphic specific defines/parameters/functions:
27  *
28  * (for SMI LynxE graphic chip)
29  *
30  * VIDEO_FB_LITTLE_ENDIAN     - framebuffer organisation default: big endian
31  * VIDEO_HW_RECTFILL	      - graphic driver supports hardware rectangle fill
32  * VIDEO_HW_BITBLT	      - graphic driver supports hardware bit blt
33  *
34  * Console Parameters are set by graphic drivers global struct:
35  *
36  * VIDEO_VISIBLE_COLS	      - x resolution
37  * VIDEO_VISIBLE_ROWS	      - y resolution
38  * VIDEO_PIXEL_SIZE	      - storage size in byte per pixel
39  * VIDEO_DATA_FORMAT	      - graphical data format GDF
40  * VIDEO_FB_ADRS	      - start of video memory
41  *
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_VIDEO_LOGO	      - display Linux Logo in upper left corner.
47  *				Use CONFIG_SPLASH_SCREEN_ALIGN with
48  *				environment variable "splashpos" to place
49  *				the logo on other position. In this case
50  *				no CONSOLE_EXTRA_INFO is possible.
51  * CONFIG_VIDEO_BMP_LOGO      - use bmp_logo instead of linux_logo
52  * CONFIG_CONSOLE_EXTRA_INFO  - display additional board information
53  *				strings that normaly goes to serial
54  *				port.  This define requires a board
55  *				specific function:
56  *				video_drawstring (VIDEO_INFO_X,
57  *					VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
58  *					info);
59  *				that fills a info buffer at i=row.
60  *				s.a: board/eltec/bab7xx.
61  *
62  * CONFIG_VIDEO_SW_CURSOR:    - Draws a cursor after the last
63  *				character. No blinking is provided.
64  *				Uses the macros CURSOR_SET and
65  *				CURSOR_OFF.
