thorpej 4044b5a41c Use separate callouts for motor-on and motor-off. Fixes a condition where the floppy driver would wedge because a motor-on timeout would be cancelled by another I/O operation cancelling a motor-off timeout. From enami tsugutomo <enami@sm.sony.co.jp>.		2000-04-07 16:58:53 +00:00

NetBSD/sun3 supports the following busses:

Bus:
mainbus -  An imaginary bus on which the other busses all reside.

obio	-  Devices on the motherboard, accessed by having their "registers"
	   mapped into the kernel's virtual address space
obmem	-  Devices on the motherboard that are mapped into main memory
	   by the hardware.  Only true of some framebuffers.
vmes	-  VME D16 space
vmel	-  VME D32 space

Devices supported:

'obio' Bus: 
Device	Type    Description
---------------------------------------------------------------------------
zs	CHAR	zilog 8530 serial ports; used for serial ports, keybd, mouse
le	IFNET	lance ethernet driver
