e668d0b2f2 Argh, isa(4), eisa(4) and mca(4) now attach to legacy(4) instead of
nexus(4) in the case of machines w/o equivalent bridges on a PCI bus.

acde0edb4d - Remove an unused write_ivars function that didn't do anything anyway.
- Return NULL from mca_alloc_resource() instead of ENOENT if we are
  passed in an empty resource list.

2237cef468 Reduce code duplication by using the GET_RESOURCE_LIST bus method and related
generic resource_list management functions.

I'll deal with the EISA bits later.

87e31f4b90 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

52caff0893 resource_list_{alloc,release}() takes a struct resource_list * as its
first arg.

0ea963e811 - Restore correct operation of bt_mca.
- Work around a problem not yet solved in the tree (but solved in mine.)

	device_get_ivars() should never be cast to a struct resource_list *
	The solution, under review, involves the creation of a
	device_get_resource_list() function.  More later.

ef98056c7d Rip out the nastiness I cribbed from the EISA bus code and actually
implement the resource management code correctly, using approved
interfaces.

While I'm here, clean up a few things.

07b096998f This is the rest of the MCA support; new_bus code to be exact.
Should we ever find ourselves on an RS/6000 this code should work
with few changes.
