MCI bluetooth coexistence method for WB222.
The rest of MCI requires a bunch more work, including adding a DMA buffer
for the MCI hardware to bounce messages in/out of and handling MCI
interrupts. But the more important part here is telling the HAL
the btcoex is enabled and MCI is in use so it configures the correct
initial bluetooth parameters in the wireless NIC and configures
things like bluetooth traffic weights and such.
So, this at least gets the HAL to do some of the right things in
configuring the inital bluetooth coexistence stuff, but doesn't
actually do full btcoex. That'll take.. some effort.
Tested:
* AR9462 (WB222), STA mode
tree's /chosen node to provide out-of-band header fields of the FDT. This
emulation is not perfect without corresponding changes to ofw_fdt_nextprop(),
but is enough to enable lookup by memory-map-parsing code.

go back through HASWELL, IVY_BRIDGE, IVY_BRIDGE_XEON and SANDY_BRIDGE
to straighten out all the missing PMCs. We also add a new pmc tool
pmcstudy, this allows one to run the various formulas from
the documents "Using Intel Vtune Amplifier XE on XXX Generation platforms" for
IB/SB and Haswell. The tool also allows one to postulate your own
formulas with any of the various PMC's. At some point I will enahance
this to work with Brendan Gregg's flame-graphs so we can flamegraph
various PMC interactions. Note the manual page also needs some
work (lots of work) but gnn has committed to help me with that ;-)

o Enable memory cycles to the bridge early (as part of the new
cbb_pci_bridge_init). This fixes the Bad VCC errors which were
caused by the code accessing the device registers with this
cleared. The suspend / resume process clears it.
o Refactor suspend / resume into bus specific code (though the ISA
code is just stubbed). This isn't strictly necessary, but makes
the initializaiton code more uniform and should be more bullet
proof in the face of variant behavior among cardbus bridges.
o Fixup comments in the power-up sequence to reflect reality. These
comments were written for one regime of power-up, but not updated
as things were revised.
o Add a paranoid small delay (100ms) to cover noisy cards powering
down.
o Fix some debugging prints to be easier to grep from dmesg.

simultaneously detaching kernel drivers on the same USB device we can
get stuck in the "usb_wait_pending_ref_locked()" function because the
conditions needed for allowing detach are not met. The "destroy_dev()"
function waits for all system calls involving the given character
device to return. Character device system calls may lock the USB
enumeration lock, which is also held when "destroy_dev()" is
called. This can sometimes lead to a deadlock not noticed by
WITNESS. The current solution is to ensure the calling thread is the
only one holding the USB enumeration lock and prevent other threads
from getting refs while a USB device detach is ongoing. This turned
out not to be sufficient. To solve this deadlock we could use
"destroy_dev_sched()" to schedule the device destruction in the
background, but then we don't know when it is safe to free() the
private data of the character device. Instead a callback function is
executed by the USB explore process to kill off any leftover USB
character devices synchronously after the USB device explore code is
finished and the USB enumeration lock is no longer locked. This makes
porting easier and also ensures us that character devices must
eventually go away after a USB device detach.
While at it ensure that "flag_iserror" is only written when "priv_mtx"
is locked, which is protecting it.

moving the handling of curcmd->error != 0 to the end of the interrupt
handler. Also make sdhci_finish_data() idempotent by moving the setting
of slot->data_done = 1 down past the point where the busdma buffer is
unmapped. This allows for the possibility that the finish routine can
get called from multiple places when handling errors.
Poll for link state when the link is down, even for interrupt capable
PHYs.
Allow PHYs to report a dubious "partial" link. If this state is seen 3
consecutive times (each check is ~1s apart) then reset the PHY. This is
a workaround for a situation where repeatedly toggling the link from the
peer gets the AEL2005 PHY into a state where it never establishes a PCS
block lock even when everything is in order.

and not automatically come back if they were gone for a short
period of time.
The isp(4) driver has a 30 second gone device timer that gets
activated whenever a device goes away. If the device comes back
before the timer expires, we don't send a notification to CAM that
it has gone away. If, however, there is a command sent to the
device while it is gone and before it comes back, the isp(4) driver
sends the command back with CAM_SEL_TIMEOUT status.
CAM responds to the CAM_SEL_TIMEOUT status by removing the device.
In the case where a device comes back within the 30 second gone
device timer window, though, we weren't telling CAM the device
came back.
So, fix this by tracking whether we have told CAM the device is
gone, and if we have, send a rescan if it comes back within the 30
second window.
ispvar.h:
In the fcportdb_t structure, add a new bitfield,
reported_gone. This gets set whenever we return a command
with CAM_SEL_TIMEOUT status on a Fibre Channel device.
isp_freebsd.c:
In isp_done(), if we're sending CAM_SEL_TIMEOUT for for a
command sent to a FC device, set the reported_gone bit.
In isp_async(), in the ISPASYNC_DEV_STAYED case, rescan the
device in question if it is mapped to a target ID and has
been reported gone.
In isp_make_here(), take a port database entry argument,
and clear the reported_gone bit when we send a rescan to
CAM.
In isp_make_gone(), take a port database entry as an
argument, and set the reported_gone bit when we send an
async event telling CAM consumers that the device is gone.

The Command Reference Number is used for precise delivery of
commands, and is part of the FC-Tape functionality set. (This is
only enabled for devices that support precise delivery of commands.)
It is an 8-bit unsigned number that increments from 1 to 255. The
commands sent by the initiator must be processed by the target in
CRN order if the CRN is non-zero.
There are certain scenarios where the Command Reference Number
sequence needs to be reset. When the target is power cycled, for
instance, the initiator needs to reset the CRN to 1. The initiator
will know this because it will see a LIP (when directly connected)
or get a logout/login event (when connected to a switch).
The isp(4) driver was not resetting the CRN when a target
went away and came back. When it saw the target again after a
power cycle, it would continue the CRN sequence where it left off.
The target would ignore the command because the CRN sequence is
supposed to be reset to 1 after a power cycle or other similar
event.
The symptom that the user would see is that there would be lots of
aborted INQUIRY commands after a tape library was power cycled, and
the library would fail to probe. The INQUIRY commands were being
ignored by the tape drive due to the CRN issue mentioned above.
isp_freebsd.c:
Add a new function, isp_fcp_reset_crn(). This will reset
all of the CRNs for a given port, or the CRNs for all LUNs
on a target.
Reset the CRNs for all targets on a port when we get a LIP,
loop reset, or loop down event.
Reset the CRN for a particular target when it arrives, is changed
or departs. This is less precise behavior than the
clearing behavior specified in the FCP-4 spec (which says
that it should be reset for PRLI, PRLO, PLOGI and LOGO),
but this is the level of information we have here. If this
is insufficient, then we will need to add more precise
notification from the lower level isp(4) code.
isp_freebsd.h:
Add a prototype for isp_fcp_reset_crn().
