3c9013e257 A couple of chip errata work-arounds refined:
- When used on a 33MHz PCI BUS, the 53C1010-66 revision 0
  requires extra clocks to be inserted in data out phase.
  Revision 1 is fixed.
- The 53C1010-33 revision 1 requires internal cycles to be
  disabled due to possible contentions on IO registers.
  Revision 2 is fixed.
Fix:
- The probing of HVD from GPIO3 bit by the driver was reversed.
  The driver could misprobe the bus mode of a 825 or 875 chip
  that was not previously initialized (no BIOS for example).

21bd1ed3bf - Don't pass in MTX_NORECURSE, as that is only used with spin mutexes and
is going away soon anyways.  Instead, don't pass MTX_RECURSE to mtx_init,
  so that WITNESS will panic if the driver mutex is recursed on.
- Use MTX_DEF in mtx_init() instead of assuming that it will be 0.

c264e80fb7 Consider that the chipset may be in ECP mode (from BIOS settings)
even if mode PS/2 is forced with bootflags. As a matter of fact,
chipsets needs some extra configuration for accessing PS/2 mode
from ECP. The current patch is only relevant for generic chipsets
since specific code is supposed to deal with this during detection.

9fa6ccfb5e Allow fxp to configure in I/O space if the user wants it and specifies
an override as a loader settable variable (fxp_iomap). fxp_iomap is
a bitmap of fxp units that should be configured to use PCI I/O space
in stead of PCI Memory space.

98ba52eadc When flipping the first entry in the qinfifo with the "next queued SCB",
we must also inform the card of this change.  Otherwise the sequencer
will traverse a corrupt list of SCBS.  The side effects of this problem
were unknown SCBs completing in the qoutfifo or worse yet, panics due
to sequencer interrupts that referenced what, to the kernel, were invalid
SCB ids.

a5847d5c27 ahc_eisa.c:
Initialize rid to 0.  This doesn't seem to make any difference
	(the driver doesn't care what rid it gets and no-one seems to
	check rid's value), but follows standard conventions.

	Pass in our device_t to ahc_alloc().  We now use device_T
	softc storage, so passing NULL results in a panic.

	Set the unit number in our softc so that the driver core
	can retrieve it.

ahc_pci.c:
	Set the unit number in our softc so that the driver core
	can retrieve it.

aic7770.c:
	Insert our softc into the list of softcs when initialization
	is successful.

aic7xxx.c:
	Remove a workaround for an aic7895 bug we will never trigger.

	Add additional diagnostic info to ahc_dump_card_state().

	Always panic the system if a sequencer assertion fails.

	AHC_SCB_BTT is a "flag" not a "feature".  Check the right
	field in the softc.

	Replace a hard coded number with a constant.

	Guard against looping forever in ahc_pause_and_flushwork().
	A hot eject or card failure may make the intstat register
	return 0xFF, so limit the number of interrupts we'll process.

	Correct the code in ahc_search_qinfifo() that guarantees that
	the sequencer will see an abort collision if the qinfifo is
	modified when a DMA is in progress.  We now do this fixup
	after modifying the queue.  This guarantees that the HSCB
	we place at the head of the queue is not the same as the
	old head.  Using "next hscb" (guaranteed not to be the
	same as the first SCB) before clearing the queue could free
	up the original head hscb to be used during a remove operation
	placing it again at the head of the qinfifo.

aic7xxx.h:
	Reduce the maximum number of outstanding commands to 253 from
	254.  To handle our output queue correctly on machines that only
	support 32bit stores, we must clear the array 4 bytes at a
	time.  To avoid colliding with a DMA write from the sequencer,
	we must be sure that 4 slots are empty when we write to clear
	the queue.  This reduces us to 253 SCBs: 1 that just completed
	and the known three additional empty slots in the queue that
	preceed it.  Yahoo was able to force this race on one of their
	systems.  Interrupts were disabled for such a time that the
	entire output queue was filled (254 entries complete without
	any processing), and our 32bit write to clear the status clobbered
	one entry.

	Add a feature tag for devices that are removable.

aic7xxx.reg:
	Never use the sequencer interrupt value of 0xF0.  We need
	to guanrantee that an INTSTAT value of 0xFF can only occur
	during card failure or a hot-eject.

	Align the busy targets table with the begining of scratch
	space.  This seems to appease a chip bug in the aic7895.

aic7xxx.seq:
	Be sure to disable select-out after a bus free event that occurs
	early in a selection.  If we don't disable select-out, we will
	believe that it is enabled even though a new selection will never
	occur.

	Move the clearing of SELDI to just before a jump.  This appeases
	another chip bug of the aic7895.

	Make the target mode command loop a bit more efficient.

	AHC_SCB_BTT is a "flag" not a "feature".  Check the right
	field in the softc.

	Properly cleanup the last SCB we tested against should we
	fail to properly find an SCB for a reselection.

	Add some additional sequencer debugging code.

aic7xxx_freebsd.c:
	Limit the driver to 253 outstanding commands per adapter.

	Guard against overflow in timeout handling.

aic7xxx_inline.h:
	AHC_SCB_BTT is a "flag" not a "feature".  Check the right
	field in the softc.

aic7xxx_pci.c:
	Set the removable feature for the apa1480 cardbus and the 29160C
	Compact PCI card.

	Don't report high byte termination information for narrow cards.

	Use a PCI read rather than a questionable delay when fetching/setting
	termination settings.

18d5982009 Update these netgraph drivers in current so that these changes can be
MFC'ed i due time.  I can't test it under current right now because
netgraph seems to do unethical things with mutexes.

musycc:
	Add status per channel.
	Reduce printf chattyness
	Keep error counters line if_mn does.
	Increase descriptor count.

if_mn:
	Support experimental unframed E1 lines.

These two drivers should share more code relating to framed channelized
TDM media in general (T1/E1/E3/T3, Sonet).  Anyone interested email me.
