[src/trunk]: src/sys/arch/luna68k/stand/boot Detect boot device on PROM load ...
details: https://anonhg.NetBSD.org/src/rev/58feaf61ee61
branches: trunk
changeset: 325748:58feaf61ee61
user: tsutsui <tsutsui%NetBSD.org@localhost>

description:
Detect boot device on PROM load command and set proper default boot device.
Also remove now unnecessary the old netboot check.
Note all addresses of boot device info set by monitor are checked by
memory dump on several LUNA ROM versions, and these addres might be
different on earlier monitor ROM versions.
Bump version to denote the visible change.
