+ *
+ * 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.
