CVS commit: src/sys/dev/pci

["Michael Lorenz" <macallan%netbsd.org@localhost>]

Module Name:    src

Modified Files:
        src/sys/dev/pci: machfb.c

Log Message:
some cleanup:
- get rid of some redundant variables ( sc_*phys and sc_*base were essentially
  the same )
- we don't access video memory directly anymore, so:
  * no more need for byte order tests
  * don't map video memory if we have a MMIO register aperture
  * get rid of various bits of support code dealing with video memory
    access
- use MMIO register aperture if available, turn off register blocks in the main
  aperture if not in use, to avoid overlap with video memory on 8MB cards
- don't scissor off access to off-screen memory. How the hell did this work on
  Rage II? Apparently Rage XL treats the scissor registers slightly different.
Now this works properly on 8MB and Rage XL boards like Sun's PGX64.
