description:
Overhaul of the ISA autoconfiguration code to support direct
configuration of devices logically attached to the ISA bus:
* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.

+ * This front-end driver is really sort of a hack. The AHA-284X likes
+ * to masquerade as an EISA device. However, on VLbus machines with
+ * no EISA signature in the BIOS, the EISA bus will never be scanned.
+ * This is intended to catch the 284X controllers on those systems
+ * by looking in "EISA i/o space" for 284X controllers.
+ *
+ * This relies heavily on i/o port accounting. We also just use the
+ * EISA macros for everything ... it's a real waste to redefine them.
+ *
+ * Note: there isn't any #ifdef for FreeBSD in this file, since the
+ * FreeBSD EISA driver handles all cases of the 284X.
