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.
