10 *
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 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
62 * initialized as an output only device.
63 * The Keyboard driver will not be
64 * set-up. This may be used, if you have
65 * no or more than one Keyboard devices
66 * (USB Keyboard, AT Keyboard).
67 *
68 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
69 * character. No blinking is provided.
70 * Uses the macros CURSOR_SET and
71 * CURSOR_OFF.
72 *
73 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability
74 * of the graphic chip. Uses the macro
75 * CURSOR_SET. ATTENTION: If booting an
76 * OS, the display driver must disable
77 * the hardware register of the graphic
78 * chip. Otherwise a blinking field is
79 * displayed.
