f7b7769172 * Factor out the object system from new-bus so that it can be used by 
non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
  takes about 40ns for a method dispatch on a 300Mhz PII which is only
  10ns slower than a direct function call on the same hardware.

This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.

25afb89b1c * Add struct resource_list* argument to resource_list_alloc and 
resource_list_release. This removes the dependancy on the
  layout of ivars.

* Move set_resource, get_resource and delete_resource from
  isa_if.m to bus_if.m.

* Simplify driver code by providing wrappers to those methods:

     bus_set_resource(dev, type, rid, start, count);
     bus_get_resource(dev, type, rid, startp, countp);
     bus_get_resource_start(dev, type, rid);
     bus_get_resource_count(dev, type, rid);
     bus_delete_resource(dev, type, rid);

* Delete isa_get_rsrc and use bus_get_resource_start instead.

* Fix a stupid typo in isa_alloc_resource reported by Takahashi
  Yoshihiro <nyan@FreeBSD.org>.

* Print a diagnostic message if we can't assign resources to a PnP
  device.

* Change device_print_prettyname() so that it doesn't print
  "(no driver assigned)-1" for anonymous devices.

4249382df0 This represents essentially a complete rewrite of the ISA PnP code. The 
new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.

This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.

cfa84f4631 * Add ivars for ISA pnp. 
* Move isa_dma* declarations to isavar.h.
* Add a method ISA_DELETE_RESOURCE() to the ISA interface.
* Tidy up include protection defines.

a3be63b3ce * Factor out the common code between the isa bus drivers for i386 and alpha. 
* Re-work the resource allocation code to use helper functions in subr_bus.c.
* Add simple isa interface for manipulating the resource ranges which can be
  allocated and remove the code from isa_write_ivar() which was previously
  used for this purpose.
