Turn off semaphores. Nobody else implements them, and there is lots of
AML out there which does totally absurd things with them, meaning that
if we try to do the right thing we are guaranteed to fail.
Use acpi_EvaluateInteger where possible.
Use FuncName rather than &FuncName when passing function addresses.
Don't evaluate the _REG method when we attach to an address space -
AcpiInstallAddressSpaceHandler does it for us.

incompletely converting simplelocks to mutexes (COM_LOCK() is supposed

- 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

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).

- Use MTX_DEF in mtx_init() instead of assuming that it will be 0.

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.
- Use proper atomic operations to make the run time initialization
controlled by svr_str_initialized be MP safe.
- Use appropriate queue(3) macros where needed.
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.

Set the unit number in our softc so that the driver core

aic7770.c:

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

Don't report high byte termination information for narrow cards.
Use a PCI read rather than a questionable delay when fetching/setting
