dc6592f82e correct SIFS setting; there is a 2usec adjustment between the calculated
value and what the hardware requires (based on inspection of INI values)

26159d4874 Reduce soft-reset assertion time from 5ms to 50us.
ATA specification declares minimal reset time of 5us. SATA keeps it, but
requires devices to handle commands transmitted even one by one without
any gap.

53963e588a Handle nForce MCP67 and MCP73 SATA controllers as AHCI. They report itself
as ATA RAID, but generic ATAPCI driver unable to detect drives there. AHCI
driver reported to handle them fine. Linux does the same.

This fixes the low "max device openings" count that has lead to poor

Extra thanks goes to Mike Tancsa at Sentex for providing a debug system for
this.

f1e1ddc3d9 acpi_cpu: fixup for PIIX4E PCI config related to C2
This is triggered only if BIOS configures ACPI_BITREG_BUS_MASTER_RLD
aka BRLD_EN_BM to 1.
Rationale:
1. we do not support C3 on PIIX4E
2. bus master activity need not break out of C2 state
3. because of CPU_QUIRK_NO_BM_CTRL quirk we may reset bus master
   status which would result in immediate break out from C2

So if you have seen
cpu0: too many short sleeps, backing off to C1
with this chipset before you may want to try cx_lowest of C2 again.

b50bb79c6a Use channel driver's attach/detach routines instead of ata_attach()/
ata_detach() to implement IOCATAATTACH/IOCATADETACH ioctls.
This will permit channel drivers to properly shutdown port hardware on channel
detach and init it on attach.

17e45e1934 Cleanup ath_hal_computetxtime's handling of 1/2 and 1/4-width channels:
o mark phy type to indicate 1/2 or 1/4-rate operation
o use phy type instead of channel attributes to identify 1/2 and 1/4-rate
  operation
o general cleanup of code including move phy constants to ah_internal.h

Eventually this code should go away and we should use the net0211 equivalents.

ebe234793b Synopsis:
If speed of link between two devices is slower than the reported max
speed of both endpoints, the current driver will fail and be unable to
negotiate.

Summary:
Test negotiated speed by reading the CSRROM into a dummy variable.
If that read fails, decrement our speed and retry.  If all else fails,
go to lowest speed possible(0).

Report speed to the user.
Add display of the Bus Info Block when debug.firewire_debug > 1
Support the Bus Info Block(1394a-2000) method of speed detection.

I also should note that I am moving "hold_count" to 0 for future
releases.

This variable determines how many bus resets to "hold" a removed
firewire device before deletion.  I don't feel this is useful and will
probably drop support for this sysctl in the future.

993b1ae273 Hold off root mounting until we've gone through the loop of our thread
almost once.  After we've configured the devices that were present the
first time through, then we know that we're done.  If the device has
other devices that are deferred, then it must do a similar dance.
This catches both PC Cards and CardBus cards.
