27 * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
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.
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.
40 * The driver uses graphic specific defines/parameters/functions:
42 * (for SMI LynxE graphic chip)
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
49 * Console Parameters are set by graphic drivers global struct:
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
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
62 * CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with
63 * delay loop in VIDEO_TSTC_FCT (i8042)
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 * Use CONFIG_SPLASH_SCREEN_ALIGN with
71 * environment variable "splashpos" to place
72 * the logo on other position. In this case
73 * no CONSOLE_EXTRA_INFO is possible.
74 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
75 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information
76 * strings that normaly goes to serial
77 * port. This define requires a board
79 * video_drawstring (VIDEO_INFO_X,
80 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
82 * that fills a info buffer at i=row.
83 * s.a: board/eltec/bab7xx.
84 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
85 * initialized as an output only device.
86 * The Keyboard driver will not be
87 * set-up. This may be used, if you have
88 * no or more than one Keyboard devices
89 * (USB Keyboard, AT Keyboard).
91 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
92 * character. No blinking is provided.
93 * Uses the macros CURSOR_SET and
96 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability
97 * of the graphic chip. Uses the macro
98 * CURSOR_SET. ATTENTION: If booting an
99 * OS, the display driver must disable
100 * the hardware register of the graphic
101 * chip. Otherwise a blinking field is
