Remove the "totally untested" comments for the ZorroII frame buffer
select macro. The card is confirmed to work in an A2000.

gcc-4.8.x unused variable fixes

branches: 1.11.6; 1.11.10;
Change old-style function defintions to C89 prototypes.

Approved by releng.

Amiga wscons/Xorg support, first phase.
Implemented wscons for CV64 and CV64/3D. Other graphics cards drivers are
prepared for it, but will not be attempted before Xorg is not running.
The wscons support is disabled by default. A GENERIC kernel should behave
like always. Use WSCONS to try out a kernel with wscons support.
Done by rkujawa@ and phx@.

branches: 1.9.78; 1.9.82;
Make the various graphics card drivers compile again.
Use casts to char* before pointer arithmetic.
Try to preserve `volatile' qualification where possible, though
uses of kvtop(), strcpy(), copyin() and copyout() gain an unfortunate
but probably unavoidable __UNVOLATILE().
Correct various instances of "void *ba, fb" to have * in front of fb as well.
Remove some redundant parenthesis pairs in some of the vga* macros.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.7.26;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

branches: 1.6.18;
Use __asm instead of asm, to keep lint happy.

o replace definitions by declarations in header files
o put definitions where due
o cleanup some types (u_int -> vaddr_t's for example)
o minor other cleanup

- ANSIfy
- remove some trailing spaces/tabs
- minor style nits

branches: 1.3.28; 1.3.32;
- recognize CV3D in Zorro-II mode.
- use board address space > 4 MB, instead of iszthreepa(), to detect Z3-mode
boards. We dont want the bus, but want the address configuration.
- s/CV64CONSOLE/CV3DCONSOLE/
- s/cv3d_zorroIII == 1/cv3d_zorroIII/ and s/cv3d_zorroIII != 1/!cv3d_zorroIII/

The Console driver works now.
Added some fixes for Zorro2 mode, but keep it still disabled.

branches: 1.1.2;
First version of the CyberVision 3D driver. This driver is based on
the CyberVision64 driver. Modified by Tobias Abt with some bugfixes
from Bernd Ernesti.
ZorroII is at the moment not supported and there is a small problem
with the Console driver where you just get a black screen, but the
system boots and you can use X11 without a problem.
