NetBSD/sys/arch/hp300/dev/grf_hy.c
thorpej 838edf78fd Snapshot of new config for NetBSD/hp300. This isn't quite finished yet.
We're about 75% there.  SCSI and HP-IB are not yet supported in a new
config kernel; some autoconfiguration hackery has to be done there, yet.
These changes are enough to network boot a diskless kernel.

New config glue is enabled with the "NEWCONFIG" kernel option.  If that
option is not present, an old config kernel will be built.  Any kernel
configured with config(8) will automatically pick up the NEWCONFIG
option from std.hp300.
