| * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel. |
| * |
| * At the moment only the 8x16 font is tested and the font fore- and |
| * background color is limited to black/white/gray colors. The Linux |
| * logo can be placed in the upper left corner and additional board |
| * information strings (that normally goes to serial port) can be drawn. |
| * |
| * The console driver can use the standard PC keyboard interface (i8042) |
| * for character input. Character output goes to a memory mapped video |
| * framebuffer with little or big-endian organisation. |
| * With environment setting 'console=serial' the console i/o can be |
| * forced to serial port. |
| * |
| * The driver uses graphic specific defines/parameters/functions: |
| * |
| * (for SMI LynxE graphic chip) |
| * |
| * CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810 |
| * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian |
| * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill |
| * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt |
| * |
| * Console Parameters are set by graphic drivers global struct: |
| * |
| * VIDEO_VISIBLE_COLS - x resolution |
| * VIDEO_VISIBLE_ROWS - y resolution |
| * VIDEO_PIXEL_SIZE - storage size in byte per pixel |
| * VIDEO_DATA_FORMAT - graphical data format GDF |
| * VIDEO_FB_ADRS - start of video memory |
| * |
| * CONFIG_I8042_KBD - AT Keyboard driver for i8042 |
| * VIDEO_KBD_INIT_FCT - init function for keyboard |
| * VIDEO_TSTC_FCT - keyboard_tstc function |
| * VIDEO_GETC_FCT - keyboard_getc function |
| * |
| * CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with |
| * delay loop in VIDEO_TSTC_FCT (i8042) |
| * |
| * CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate |
| * CONFIG_CONSOLE_TIME - display time/date in upper right |
| * corner, needs CONFIG_CMD_DATE and |
| * CONFIG_CONSOLE_CURSOR |
| * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner. |
| * Use CONFIG_SPLASH_SCREEN_ALIGN with |
| * environment variable "splashpos" to place |
| * the logo on other position. In this case |
| * no CONSOLE_EXTRA_INFO is possible. |
| * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo |
| * CONFIG_CONSOLE_EXTRA_INFO - display additional board information |
| * strings that normaly goes to serial |
| * port. This define requires a board |
| * specific function: |
| * video_drawstring (VIDEO_INFO_X, |
| * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, |
| * info); |
| * that fills a info buffer at i=row. |
| * s.a: board/eltec/bab7xx. |
| * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be |
| * initialized as an output only device. |
| * The Keyboard driver will not be |
| * set-up. This may be used, if you have |
| * no or more than one Keyboard devices |
| * (USB Keyboard, AT Keyboard). |
| * |
| * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last |
| * character. No blinking is provided. |
| * Uses the macros CURSOR_SET and |
| * CURSOR_OFF. |
| * |
| * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability |
| * of the graphic chip. Uses the macro |
| * CURSOR_SET. ATTENTION: If booting an |
| * OS, the display driver must disable |
| * the hardware register of the graphic |
| * chip. Otherwise a blinking field is |
| * displayed. |
