System: NetBSD lestat 1.3C NetBSD 1.3C (LESTAT) #125: Sat Feb 14 17:54:05 PST 1998 thorpej@lestat:/tmp_mnt/dracul/u5/netbsd/src/sys/arch/sparc/compile/LESTAT sparc


>Description:
	Several drivers which now have multiple attachments for devices in
	one file unconditionally reference functions in objects which may
	not be included in a trimmed-down kernel.
>How-To-Repeat:
	Attempt to build a NetBSD/sparc kernel with the following kernel
	configuration file:

>Fix:
	For every driver that has multiple attachments, the file needs to
	be split like so (example is clock.c):

	Mostek clock common code:	clock.c
	mainbus attachment:		clock_mainbus.c
	obio attachment:		clock_obio.c

	Sun timer common code:		timer.c
	mainbus attachment		timer_mainbus.c
	obio attachment			timer_obio.c

	Intersil clock common code:	oclock.c
	(Only one [obio] attachment for this device, so it can stay in
	oclock.c)

	This needs to be done for all devices with multiple attachments.
