Eliminate all mentions of rasops_info from igsfb_ioctl(), we have all
the information in igsfb_devconfig now. It's semantically correct to
serve that info from there, not from a cached copy in rasops_info.
Fail cursor related ioctls with EBUSY while in text mode.
Don't do uvm_useracc checks before copyout, instead check copyout()
return value directly.
Minor cleanups.
Setup sequence obtained from Krups OFW with some CyberPro-specific
magic from Linux driver. The driver still has a lot of hardcoded
stuff, but it is useful enough to bring up wscons on netwinder.
XXX: Proper console attachment needs to be written (the driver was
originally developed on sparc, where our approach to attaching console
is totally different).
Caveat emptor!
Always init chip via I/O space.
Map only I/O registers we actually need.
Automatically detect if we need to do bswapping
Add (untested) code to use automagic bswap on CyberPro.
Report video memory amount.
Report if/how bswapping is done.
