fbdev: remove cyblafb driver 



A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.

Changes to the tridentfb driver:

- FBINFO_READS_FAST added to the tridentfb.  The cyblafb used a blitter
  for scrolling which is faster than color expansion on Cyberblade
  chipsets.  The blitter is slower on a discrete Blade3D core.  Use the
  blitter for scrolling in the tridentfb only for integrated Blade3D
  cores.  Now, scrolling speed is about equal for the tridentfb and the
  cyblafb.

- a copyright notice addition is done on request of Jani Monoses (the
  first author of the tridentfb).

Tested on AGP Blade3D card and PCChips
M787CLR motherboard: VIA C3 cpu +
VT8601 north  bridge (aka Cyberblade/i1).

Bugs

====



I currently don't know of any bug. Please do send reports to:

 - linux-fbdev-devel@lists.sourceforge.net

 - Knut_Petersen@t-online.de.





Untested features

=================



All LCD stuff is untested. If it worked in tridentfb, it should work in

cyblafb. Please test and report the results to Knut_Petersen@t-online.de.

Apollo PLE 133 Chipset VT8601A North Bridge Datasheet, Rev. 1.82, October 22,

2001, available from VIA:



	http://www.viavpsd.com/product/6/15/DS8601A182.pdf



The datasheet is incomplete, some registers that need to be programmed are not

explained at all and important bits are listed as "reserved". But you really

need the datasheet to understand the code.  "p. xxx" comments refer to page

numbers of this document.



XFree/XOrg drivers are available and of good quality, looking at the code

there is a good idea if the datasheet does not provide enough information

or if the datasheet seems to be wrong.

#   Sample fb.modes file

#

#	Provides an incomplete list of working modes for

#	the cyberblade/i1 graphics core.

#

#	The value 4294967256 is used instead of -40. Of course, -40 is not

#	a really reasonable value, but chip design does not always follow

#	logic. Believe me, it's ok, and it's the way the BIOS does it.

#

#	fbset requires 4294967256 in fb.modes and -40 as an argument to

#	the -t parameter. That's also not too reasonable, and it might change

#	in the future or might even be differt for your current version.
