-* linux/drivers/video/cyberfb.c -- CyberVision64 frame buffer device

-* This file is based on two CyberVision64 frame buffer device drivers
-*
-* The second CyberVision64 frame buffer device (cvision.c cvision_core.c):
-*
-*   Copyright (c) 1997 Antonio Santos
-*
-* Released as a patch to 2.1.35, but never included in the source tree.
-* This is based on work from the NetBSD CyberVision64 frame buffer driver 
-* and support files (grf_cv.c, grf_cvreg.h, ite_cv.c):
-* Permission to use the source of this driver was obtained from the
-* author Michael Teske by Alan Bair.

-* History:
-*   - 22 Dec 95: Original version by Martin Apel
-*   - 05 Jan 96: Geert: integration into the current source tree
-*   - 01 Aug 98: Alan: Merge in code from cvision.c and cvision_core.c
-* $Log: cyberfb.c,v $
-* Revision 1.6  1998/09/11 04:54:58  abair
-* Update for 2.1.120 change in include file location.
-* Clean up for public release.
-*
-* Revision 1.5  1998/09/03 04:27:13  abair
-* Move cv64_load_video_mode to cyber_set_video so a new video mode is install
-* with each change of the 'var' data.
-*
-* Revision 1.4  1998/09/01 00:31:17  abair
-* Put in a set of default 8,16,24 bpp modes and map cyber8,16 to them.
-* Update operations with 'par' to handle a more complete set of parameter
-* values for encode/decode process.
-*
-* Revision 1.3  1998/08/31 21:31:33  abair
-* Swap 800x490 for 640x480 video mode and more cleanup.
-* Abandon idea to resurrect "custom" mode setting via kernel opts,
-* instead work on making use of fbset program to do this.
-*
-* Revision 1.2  1998/08/31 06:17:08  abair
-* Make updates for changes in cyberfb.c released in 2.1.119
-* and do some cleanup of the code.
-*
-* Revision 1.1  1998/08/29 18:38:31  abair
-* Initial revision
-*
-* Revision 1.3  1998/08/17 06:21:53  abair
-* Remove more redundant code after merging in cvision_core.c
-* Set blanking by colormap to pale red to detect this vs trying to
-* use video blanking. More formating to Linux code style.
-*
-* Revision 1.2  1998/08/15 17:51:37  abair
-* Added cvision_core.c code from 2.1.35 patches.
-* Changed to compile correctly and switch to using initialization
-* code. Added debugging and dropping of duplicate code.
