10  * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
11  *
12  * At the moment only the 8x16 font is tested and the font fore- and
13  * background color is limited to black/white/gray colors. The Linux
14  * logo can be placed in the upper left corner and additional board
15  * information strings (that normally goes to serial port) can be drawn.
16  *
17  * The console driver can use a keyboard interface for character input
18  * but this is deprecated. Only rk51 uses it.
19  *
20  * Character output goes to a memory-mapped video
21  * framebuffer with little or big-endian organisation.
22  * With environment setting 'console=serial' the console i/o can be
23  * forced to serial port.
24  *
25  * The driver uses graphic specific defines/parameters/functions:
26  *
27  * (for SMI LynxE graphic chip)
28  *
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  * VIDEO_KBD_INIT_FCT	      - init function for keyboard
42  * VIDEO_TSTC_FCT	      - keyboard_tstc function
43  * VIDEO_GETC_FCT	      - keyboard_getc function
44  *
45  * CONFIG_VIDEO_LOGO	      - display Linux Logo in upper left corner.
46  *				Use CONFIG_SPLASH_SCREEN_ALIGN with
47  *				environment variable "splashpos" to place
48  *				the logo on other position. In this case
49  *				no CONSOLE_EXTRA_INFO is possible.
50  * CONFIG_VIDEO_BMP_LOGO      - use bmp_logo instead of linux_logo
51  * CONFIG_CONSOLE_EXTRA_INFO  - display additional board information
52  *				strings that normaly goes to serial
53  *				port.  This define requires a board
54  *				specific function:
55  *				video_drawstring (VIDEO_INFO_X,
56  *					VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
57  *					info);
58  *				that fills a info buffer at i=row.
59  *				s.a: board/eltec/bab7xx.
60  *
61  * CONFIG_VIDEO_SW_CURSOR:    - Draws a cursor after the last
62  *				character. No blinking is provided.
63  *				Uses the macros CURSOR_SET and
64  *				CURSOR_OFF.
