thorpej 769a499800 New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

christos 86373f8cf9 backout kprintf changes 1996-10-13 01:37:04 +00:00
christos 58953408cb printf -> kprintf, sprintf -> ksprintf 1996-10-10 22:04:48 +00:00
cgd 2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

mycroft cec36bf8d5 Use intr.h. 1996-05-12 23:51:23 +00:00
christos d21e608c6b Make those compile again; they were missing a declaration for bc.
Also fix prototypes.

cgd a610e9d471 include <sys/termios.h> to make comvar.h happy 1996-04-15 18:55:23 +00:00
cgd 51e85d07b9 update for addition of a machine-dependent cookie as the first argument
to isa_intr_{,dis}establish().
1996-04-11 22:27:59 +00:00
cgd 402f77d443 remove tricky open-coded variants of config_found(), by using the
child device pointer now returned by config_found().  (previously,
the code played games to get that pointer; now they are unnecesary.)

thorpej 6d9ea4cf59 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

cgd 85286bff2f convert these to use new <machine/bus.h> interfaces. This involved
substantial reworking of the multi-port drivers, as they need to frob
bits in the io-port spaces of their children.  As a result, the
commulti->com attachment interface is substantially more complex.
(This may be fixable in the future by making some of the code common,
but as long as io-port allocation checking is planned, it's necessary.)

cgd 85288c6a61 Include comvar.h, for comprobe1() prototype and for commulti_attach_args.
Remove multiple identical definitions for the arg struct used by multiport
boards' to attach slave com ports.

cgd 645d83b763 minor cleanup. mostly: use COM_NPORTS and a new (driver-specific) NSLAVES
macro where appropriate.  No point in hard-coding numbers in multiple places.
At the very least, this makes the drivers slightly easier to diff/understand.

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 7491d6cbe5 if subdevices specified with wildcarded unit number, config_attach()
can change the cf_unit, so save it before attach and use saved value.

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...

configured.

cgd c24c16f35f add AST-style serial multiport support, from Roland McGrath
<roland@frob.com>.  Needs light clean by Mr. I386, but mostly
OK.
