wdenk 8bde7f776c * Code cleanup: 
- remove trailing white space, trailing empty lines, C++ comments, etc.
  - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)

* cfb_console.c
*
* 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 normaly goes to serial port) can be drawed.
*
* 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)
CFG_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
CONFIG_CONSOLE_TIME - display time/date in upper right corner,
needs CFG_CMD_DATE and CONFIG_CONSOLE_CURSOR
CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner
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 initialised
as an output only device. The Keyboard driver
will not be set-up. This may be used, if you
have none 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
