ac0c5aaf01 Use haveseen_ioport() which is now connected up to the resource manager. 1999-05-08 18:20:57 +00:00

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

07353d4247 o enable plug and play support for the aha driver. Given the cumbersome
pnp system in freebsd, I'm not sure how useful this will be, but my
  1542CP seems to work well in plug and play mode and does seem to
  probe correctly at all the oddball addresses/irq/drqs that I tried.
  [[
     I was unable to get /kernel.conf or /kernel.config to read in, so
     I wasn't able to verify that this method of userconfig works.  that's
     one thing that makes pnp so hard to use in the current scheme.
     Pointers to the right new way of doing this accepted.

o Add some kludges to maybe bring support for 1540A/1542A into the
  driver.  Since I have no 154xA cards, and the only person I know
  that has them hasn't given me feedback, I'm making this commit
  blind.
o Honor unit numbers that are in the config file now.  This allows one
  to hard wire the unit numbers (and have high unit numbers for plug
  and pray devices, which can't seem to be hardwired) and have the
  cards not migrate from aha1 -> aha0 should aha0 go on the fritz.  I
  didn't verify that hard wired scsi busses would work, but did verify
  that hard wired aha addresses did work to a limited extent.  Both
  aha0 and aha1 must be hardwired, or when the card that was in aha0
  goes away, the probe for aha0 might pick up the card that otherwise
  would have been aha1.

bb415a7e88 Fix breakage introduced by last patch. bde has added CC_QUIET flag to
hasseen_isadev so this will be less noisy when conflicts do exist.
Also eliminate redundant warnings about conflicts.

19bed41a5d Fix conficts in probe:
o For bt and aha only probe the one I/O range if a specific I/O is specified
  in the config file.
o Don't even try to probe I/O ranges that have been seen already.
o If we conflict with an IRQ or DRQ, then fail the probe.

f28d6834e1 Removed unused include of "ioconf.h" again. The CAM changes made ioconf.h
empty but regressed to including it here.
