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 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. 23 * 24 * The driver uses graphic specific defines/parameters/functions: 25 * 26 * (for SMI LynxE graphic chip) 27 * 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 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 * 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 45 * 46 * CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with 47 * delay loop in VIDEO_TSTC_FCT (i8042) 48 * 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 62 * specific function: 63 * video_drawstring (VIDEO_INFO_X, 64 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 65 * info); 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). 74 * 75 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 76 * character. No blinking is provided. 77 * Uses the macros CURSOR_SET and 78 * CURSOR_OFF. 79 * 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.
