 1.3  25-Jul-2014  dholland Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.
 1.2  16-Mar-2014  dholland branches: 1.2.2;
Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
 1.1  20-Nov-2011  tsutsui branches: 1.1.6; 1.1.10; 1.1.14;
Add preliminary PROM internal function based framebuffer console support,
which was demonstrated at Open Source Conference 2011 Kansai @ Kyoto
back in July:
http://www.NetBSD.org/gallery/events.html#opensourceconf2011-Kansai

- map 0xc0000000-0xffffffff PA region (which is mirror of PA 0x0-0x3fffffff)
to the same VA via %tt0 and %tt1 registers and move KVA space accordingly
(like luna68k does for its devices)
- save trap #0 vector for PROM function calls in early bootstrap
and register it to trap #14 to call it from kernel for console output
- add dumb romcall based tty attachment taken from src/sys/dev/ofw/ofcons.c
- add rom function call stubs from news68k/stand/common/romcalls.S
- remove IIOV() macro for device registers where now mapped PA==VA via %tt1

XXX: romcons is not enabled yet because there is no generic interface
XXX: to attach wskbd(4) to non wsdisplay(4) devices like this romcons.
