+ * Machine-dependent portions of ISA PnP bus autoconfiguration.
+ *
+ * N.B. This file exists mostly to get around some lameness surrounding
+ * the PnP spec.  ISA PnP registers live where some `normal' ISA
+ * devices do, but are e.g. write-only registers where the normal
+ * device has a read-only register.  This breaks in the presence of
+ * i/o port accounting.  This file takes care of mapping ISA PnP
+ * registers without actually allocating them in extent maps.
+ *
+ * Since this is a machine-dependent file, we make all sorts of
+ * assumptions about bus.h's guts.  Beware!
+ *
+ * Note: We just use bus_space{,un}map() here, because we need to
+ * actually map the space into KVA space.  This works because we
+ * don't do space accounting (we'd need a back-door to bypass it
+ * if we did!).
