49e7158ab9 x68k needs config_cfdriver_lookup() to initialize its console.
XXX ad-hoc way?

194d7347bc Implement config_attach_pseudo(), which creates an instance of
a pseudo-device which behaves like a normal device in the device
tree, including the capability to have children.

d90d300b7b Overhaul the way cfattach structures are looked up. The cfdata entry
now carries the name of the attachment (e.g. "tlp_pci" or "audio"),
and cfattach structures are registered at boot time on a per-driver
basis.  The cfdriver and cfattach pointers are cached in the device
structure when attached.

2b99f7cc34 Add a generic config finalization hook, to be called once all real
devices have been discovered.  All finalizer routines are iteratively
invoked until all of them report that they have done no work.

Use this hook to fix a latent bug in RAIDframe autoconfiguration of
RAID sets exposed by the rework of SCSI device discovery.

1a6b241b1d Add a config_init() function to initialize the config data structures.
Normally this is called by configure(), but some ports (amiga, atari,
x68k) need to do this early because of how they find the console.

97741f5198 Some ports (like Amiga) want to use the config machinery VERY early
(to initialize the console).  Support this when doing cfdriver lookup.

6c88de3b53 Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller.  Use it
rather than invoking cfattach->ca_match directly.

d1ad2ac4f2 Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.

fc0fe0347d Overhaul the way parent attachments are specified; instead of using
a vector of indices into the cfdata table to specify potential parents,
record the interface attributes that devices have and add a new "parent
spec" structure which lists the iattr, as well as optionally listing
specific parent device instances.

See:

    http://mail-index.netbsd.org/tech-kern/2002/09/25/0014.html

...for a detailed description.

While here, const poison some things, as suggested by Matt Thomas.

5aa64075cc Add a `config_pending' semaphore to block mounting of the root file system
until all device driver discovery threads have had a chance to do their
work.  This in turn blocks initproc's exec of init(8) until root is
mounted and process start times and CWD info has been fixed up.

Addresses kern/9247.

71a030cab6 avoid 'marching unit numbers' for cloning devices. (e.g., previously,
if you com* at pcmcia?, and com3 and com4 as pcmcia cards, and removed
and reinserted the card that was com3, it would become com5.  if you then
removed and reinserted com4, it would become com6.  etc.)  Now, instead
of incrementing FSTATE_STAR configuration entries for a driver when
a cloning instance is attached, leave it alone, and scan the device softc
array (starting at the first cloning unit number) for units which are
available for use.  This wastes a tiny bit of time (can require a linear
scan of the softc table for the device), but device attachment should be
relatively infrequent and the number of units of each type of device
is never particularly large anyway.

ab1b371163 Implement config_detach(), mostly from Chris Demetriou, modified slightly
by Ken Hornstein and myself.

Add flags to struct device, and define one as "active".  Devices are
initially active from config_attach().  Their active state may be changed
via config_activate() and config_deactivate().

These new functions assume that the device being manipulated will recursively
perform the action on its children.

Together, config_deactivate() and config_detach() may be used to implement
interrupt-driven device detachment.  config_deactivate() will take care of
things that need to be performed at interrupt time, and config_detach()
(which must run in a valid thread context) finishes the job, which may
block.
