11 * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
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.
18 * The console driver can use the standard PC keyboard interface (i8042)
19 * for character input. Character output goes to a memory mapped video
20 * framebuffer with little or big-endian organisation.
21 * With environment setting 'console=serial' the console i/o can be
22 * forced to serial port.
24 * The driver uses graphic specific defines/parameters/functions:
26 * (for SMI LynxE graphic chip)
28 * CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
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
33 * Console Parameters are set by graphic drivers global struct:
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
41 * CONFIG_I8042_KBD - AT Keyboard driver for i8042
42 * VIDEO_KBD_INIT_FCT - init function for keyboard
43 * VIDEO_TSTC_FCT - keyboard_tstc function
44 * VIDEO_GETC_FCT - keyboard_getc function
46 * CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with
47 * delay loop in VIDEO_TSTC_FCT (i8042)
49 * CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
50 * CONFIG_CONSOLE_TIME - display time/date in upper right
51 * corner, needs CONFIG_CMD_DATE and
52 * CONFIG_CONSOLE_CURSOR
53 * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner.
54 * Use CONFIG_SPLASH_SCREEN_ALIGN with
55 * environment variable "splashpos" to place
56 * the logo on other position. In this case
57 * no CONSOLE_EXTRA_INFO is possible.
58 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
59 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information
60 * strings that normaly goes to serial
61 * port. This define requires a board
63 * video_drawstring (VIDEO_INFO_X,
64 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
66 * that fills a info buffer at i=row.
67 * s.a: board/eltec/bab7xx.
68 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
69 * initialized as an output only device.
70 * The Keyboard driver will not be
71 * set-up. This may be used, if you have
72 * no or more than one Keyboard devices
73 * (USB Keyboard, AT Keyboard).
75 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
76 * character. No blinking is provided.
77 * Uses the macros CURSOR_SET and
80 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability
81 * of the graphic chip. Uses the macro
82 * CURSOR_SET. ATTENTION: If booting an
83 * OS, the display driver must disable
84 * the hardware register of the graphic
85 * chip. Otherwise a blinking field is
