/*
* Machine-dependent code provides a list of these to describe
* devices on the ISA bus which should be attached via direct
* configuration.
*
* All of this information is dynamically allocated, so that
* the ISA bus driver may free all of this information if the
* bus does not support dynamic attach/detach of devices (e.g.
* on a docking station).
*
* Some info on the "ik_key" field: This is a unique number for
* each knowndev node. If, when we need to re-enumerate the
* knowndevs, we discover that a node with key N is in the old
* list but not in the new, the device has disappeared. Similarly,
* if a node with key M is in the new list but not in the old,
* the device is new. Note that the knowndevs list must be
* sorted in ascending "key" order.
