83c41143ca Reimplement how PCI-PCI bridges manage their I/O windows. Previously the
driver would verify that requests for child devices were confined to any
existing I/O windows, but the driver relied on the firmware to initialize
the windows and would never grow the windows for new requests.  Now the
driver actively manages the I/O windows.

This is implemented by allocating a bus resource for each I/O window from
the parent PCI bus and suballocating that resource to child devices.  The
suballocations are managed by creating an rman for each I/O window.  The
suballocated resources are mapped by passing the bus_activate_resource()
call up to the parent PCI bus.  Windows are grown when needed by using
bus_adjust_resource() to adjust the resource allocated from the parent PCI
bus.  If the adjust request succeeds, the window is adjusted and the
suballocation request for the child device is retried.

When growing a window, the rman_first_free_region() and
rman_last_free_region() routines are used to determine if the front or
end of the existing I/O window is free.  From using that, the smallest
ranges that need to be added to either the front or back of the window
are computed.  The driver will first try to grow the window in whichever
direction requires the smallest growth first followed by the other
direction if that fails.

Subtractive bridges will first attempt to satisfy requests for child
resources from I/O windows (including attempts to grow the windows).  If
that fails, the request is passed up to the parent PCI bus directly
however.

The PCI-PCI bridge driver will try to use firmware-assigned ranges for
child BARs first and only allocate a "fresh" range if that specific range
cannot be accommodated in the I/O window.  This allows systems where the
firmware assigns resources during boot but later wipes the I/O windows
(some ACPI BIOSen are known to do this) to "rediscover" the original I/O
window ranges.

The ACPI Host-PCI bridge driver has been adjusted to correctly honor
hw.acpi.host_mem_start and the I/O port equivalent when a PCI-PCI bridge
makes a wildcard request for an I/O window range.

The new PCI-PCI bridge driver is only enabled if the NEW_PCIB kernel option
is enabled.  This is a transition aide to allow platforms that do not
yet support bus_activate_resource() and bus_adjust_resource() in their
Host-PCI bridge drivers (and possibly other drivers as needed) to use the
old driver for now.  Once all platforms support the new driver, the
kernel option and old driver will be removed.

7df304f3e0 Stop linking against a direct-mapped virtual address and instead
use the PBVM. This eliminates the implied hardcoding of the
physical address at which the kernel needs to be loaded. Using the
PBVM makes it possible to load the kernel irrespective of the
physical memory organization and allows us to replicate kernel text
on NUMA machines.

While here, reduce the direct-mapped page size to the kernel's
page size so that we can support memory attributes better.

9f25ad52ce Introduce AR9130 (HOWL) WMAC support to the FreeBSD HAL.
The AR9130 is an AR9160/AR5416 family WMAC which is glued directly
to the AR913x SoC peripheral bus (APB) rather than via a PCI/PCIe
bridge.

The specifics:

* A new build option is required to use the AR9130 - AH_SUPPORT_AR9130.
  This is needed due to the different location the RTC registers live
  with this chip; hopefully this will be undone in the future.
  This does currently mean that enabling this option will break non-AR9130
  builds, so don't enable it unless you're specifically building an image
  for the AR913x SoC.

* Add the new probe, attach, EEPROM and PLL methods specific to Howl.

* Add a work-around to ah_eeprom_v14.c which disables some of the checks
  for endian-ness and magic in the EEPROM image if an eepromdata block
  is provided. This'll be fixed at a later stage by porting the ath9k
  probe code and making sure it doesn't break in other setups (which
  my previous attempt at this did.)

* Sprinkle Howl modifications throughput the interrupt path - it doesn't
  implement the SYNC interrupt registers, so ignore those.

* Sprinkle Howl chip powerup/down throughout the reset path; the RTC methods
  were

* Sprinkle some other Howl workarounds in the reset path.

* Hard-code an alternative setup for the AR_CFG register for Howl, that
  sets up things suitable for Big-Endian MIPS (which is the only platform
  this chip is glued to.)

This has been tested on the AR913x based TP-Link WR-1043nd mode, in
legacy, HT/20 and HT/40 modes.

Caveats:

* 2ghz has only been tested. I've not seen any 5ghz radios glued to this
  chipset so I can't test it.

* AR5416_INTERRUPT_MITIGATION is not supported on the AR9130. At least,
  it isn't implemented in ath9k. Please don't enable this.

* This hasn't been tested in MBSS mode or in RX/TX block-aggregation mode.

97b53e3634 Switch the GENERIC kernels for all architectures to the new CAM-based ATA
stack. It means that all legacy ATA drivers are disabled and replaced by
respective CAM drivers. If you are using ATA device names in /etc/fstab or
other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise
with tunables, see cam(4)).

ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool
for management. Instead of /dev/arX device names, use /dev/raid/rX.

70df4233cd Compile in in_cksum* implementations for both IPv6 and IPv6.
While in_pseudo() etc. is often used in offloading feature support,
in_cksum() is mostly used to fix some broken hardware.

Keeping both around for the moment allows us to compile NIC drivers
even in an IPv6 only environment without the need to mangle them
with #ifdef INETs in a way they are not prepared for.  This will
leave some dead code paths that will not be exercised for IPv6.

27afdbaa51 Introduce geom_map, a GEOM provider designed for use by
embedded flash stores.

Some devices - notably those with uboot - don't have an
explicit partition table (eg like Redboot's FIS.)
geom_map thus provides an easy way to export the hard-coded
flash layout as geom providers for use by filesystems and
other tools.

It also includes a "search" function which allows for
dynamic creation of partition layouts where the device only
has a single hard-coded partition. For example, if
there is a "kernel+rootfs" partition, a single image can
be created which appends the rootfs after the kernel with
an appropriate search string. geom_map can be told to
search for said search string and create a partition
beginning after it.

1c675a3bc3 The new binutils has correctly redefined MAXPAGESIZE on amd64 as 0x200000
instead of 0x100000.  As a side effect, an amd64 kernel now loads at
physical address 0x200000 instead of 0x100000.  This is probably for the
best because it avoids the use of a 2MB page mapping for the first 1MB of
the kernel that also spans the fixed MTRRs.  However, getmemsize() still
thinks that the kernel loads at 0x100000, and so the physical memory between
0x100000 and 0x200000 is lost.  Fix this problem by replacing the hard-wired
constant in getmemsize() by a symbol "kernphys" that is defined by the

  This required a way to alter the XMITS configuration in case a PCI-X
  device is found further down the device tree so the sparc64 specific
  ofw_pci kobj was revived with a ofw_pci_setup_device method, which is
  called by the ofw_pcibus code for every device added.
- A closer inspection of the OpenSolaris code indicates that consistent
  DMA flushing/syncing as well as the block store workaround should be
  applied with every BUS_DMASYNC_POSTREAD instead of in a wrapper around
  interrupt handlers for devices behind PCI-PCI bridges only as suggested
  by the documentation (code for the latter actually exists in OpenSolaris
  but is disabled by default), which also makes more sense.

  this solves the crashes seen when using the the on-board Casinni NICs
  of Sun Fire V480 equipped with centerplanes other than 501-6780 or

Add new RAID GEOM class, that is going to replace ataraid(4) in supporting
various BIOS-based software RAIDs. Unlike ataraid(4) this implementation
does not depend on legacy ata(4) subsystem and can be used with any disk
drivers, including new CAM-based ones (ahci(4), siis(4), mvs(4), ata(4)
with `options ATA_CAM`). To make code more readable and extensible, this
implementation follows modular design, including core part and two sets
of modules, implementing support for different metadata formats and RAID
levels.

Support for such popular metadata formats is now implemented:
Intel, JMicron, NVIDIA, Promise (also used by AMD/ATI) and SiliconImage.

Such RAID levels are now supported:
RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT.

For any all of these RAID levels and metadata formats this class supports
full cycle of volume operations: reading, writing, creation, deletion,
disk removal and insertion, rebuilding, dirty shutdown detection
and resynchronization, bad sector recovery, faulty disks tracking,
hot-spare disks. For Intel and Promise formats there is support multiple
volumes per disk set.

0355a8b24b Fix switching to physical mode as part of calling into EFI runtime
services or PAL procedures. The new implementation is based on
specific functions that are known to be called in certain scenarios
only. This in particular fixes the PAL call to obtain information
about translation registers. In general, the new implementation does
not bank on virtual addresses being direct-mapped and will work when
the kernel uses PBVM.

When new scenarios need to be supported, new functions are added if
the existing functions cannot be changed to handle the new scenario.
If a single generic implementation is possible, it will become clear
in due time.

While here, change bootinfo to a pointer type in anticipation of
future development.
