thorpej e32158478e Correct a couple of comments ... port 0x84 produces a 1.25us delay when
read, not 2.5us.  (I must have been confused; thanks Charles, for
correcting me.)

thorpej 6fb58044fd Map port 0x84 (which is used to generate a 2.6us delay) in isaattach().
Since this port is needed by at least a few drivers, export its i/o handle
via isa_attach_args.

cgd a391172983 include a machine-specific header from ARCH/isa/isa_machdep.h, to define
the isa_chipset_tag_t type, and to define or prototype:
	isa_attach_hook()
	isa_intr_establish()
	isa_intr_disestablish()
i.e. the machine-dependent functions to be used my MI ISA code.
Remove prototypes for the latter two functions from this file.

cgd 2b96f0705b delete unused cruft (the 'software conventions' chunk). 1996-03-16 02:00:43 +00:00
cgd 5087096150 pass a bus_chipset_tag_t (defined in <machine/bus.h>) to the bus when
attaching, and to the devices when attaching them.  #include <machine/bus.h>
to make this backward compatible with old #include requirements.
Also, clean up idempotency so that isa/eisa/pci "var.h" headers are
consistent (make them all idempotent).

cgd 3ca5707161 make ISA bus match/attach, and sub-device configuration machine-independent. 1996-02-28 01:43:45 +00:00
mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

cgd 8a640328ed clean up several ISA device interfaces: autoconfiguration, header
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...

mycroft 5eb99ad76e New autoconfig mechanism. Hacked at the moment to use old config(8), but
look mostly like config.new to drivers.
