cgd b005a8ee10 move cominit() prototype to comvar.h, so that ports which use 'com'
for serial console, but don't use the (i386-specific)
comcninit()/comcnprobe() functions, can do the right thing.

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 d53d6cd545 Move comintr() prototype to comvar.h; needed by the multi-port cards. 1996-05-05 19:50:44 +00:00
cgd b6549d493d define and export the global variable "comconscflag", the default tty
'cflag' for the console.  Normally set to TTYDEF_CFLAG, may be
overridden by machine-dependent console attachment code, as necessary.
(Alpha uses it to set cs8 -parenb.)  Files including comvar.h now
need to include <sys/termios.h>, because comconscflag is of type
tcflag_t.

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 56edbfc4f9 define the common structure used to attach 'com' units as slaves to
multiport cards.  prototype comprobe1(), which is used by multiport card
drivers.
