Change all the sample kernel configurations to use
NFSCL, NFSD instead of NFSCLIENT, NFSSERVER since
NFSCL and NFSD are now the defaults. The client change is
needed for diskless configurations, so that the root
mount works for fstype nfs.

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.

Break out the ath PCI logic into a separate device/module.

Introduce the AHB glue for Atheros embedded systems. Right now it's
hard-coded for the AR9130 chip whose support isn't yet in this HAL;
it'll be added in a subsequent commit.

Kernel configuration files now need both 'ath' and 'ath_pci' devices; both
modules need to be loaded for the ath device to work.

Hook up the five gpio pins on the Avila board to the gpio framework. There are
actually 16 I/O lines but the other ones are used for system devices and
interrupts.

The IXP4XX platform can set interrupts on these pins for
high/low/rising/falling/transitional but this is not implemented yet.

The Cambria has the same interface but as all the pins are assigned to system
functions the gpio header is toggled via a PLD on the i2c bus and is not
supported by this commit.

Adjust style (following the already existing rules) for the newly
introduced option DEADLKRES.

Reported by: danfe, julian, avg

Add the options DEADLKRES (introducing the deadlock resolver thread) in
the 'debugging' section of any HEAD kernel and enable for the mainstream
ones, excluding the embedded architectures.
It may, of course, enabled on a case-by-case basis.

Intel XScale hwpmc(4) support.

This brings hwpmc(4) support for 2nd and 3rd generation XScale cores.
Right now it's enabled by default to make sure we test this a bit.
When the time comes it can be disabled by default.
Tested on Gateworks boards.

Delete the old USB stack. The new stack has settled in and has all the

- Use "device\t" and "options \t" for consistency.

revert unintended change

Hoist 802.11 encapsulation up into net80211:
o call ieee80211_encap in ieee80211_start so frames passed down to drivers
are already encapsulated
o remove ieee80211_encap calls in drivers
o fixup wi so it recreates the 802.3 head it requires from the 802.11
header contents
o move fast-frame aggregation from ath to net80211 (conditional on
IEEE80211_SUPPORT_SUPERG):
- aggregation is now done in ieee80211_start; it is enabled when the
packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames
are held on a staging queue according to ieee80211_ffagemax
(net.wlan.ffagemax) to wait for a frame to combine with
- drivers must call back to age/flush the staging queue (ath does this
on tx done, at swba, and on rx according to the state of the tx queues
and/or the contents of the staging queue)
- remove fast-frame-related data structures from ath
- add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle
per-node fast-frames state (we reuse 11n tx ampdu state)
o change ieee80211_encap calling convention to include an explicit vap
so frames coming through a WDS vap are recognized w/o setting M_WDS

With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

Remove ATH_SUPPORT_TDMA and use IEEE80211_SUPPORT_TDMA instead. It
doesn't make much sense to configure driver support w/o net80211.
Note this means ath now depends on opt_wlan.h.

add cfid and geom_redboot

enable tdma support by default; many people using these boards
are using them to setup tdma p2p links

legacy USB is required on these platforms at the moment

Change over the usb kernel options to the new stack (retaining existing
naming). The old usb stack can be compiled in my prefixing the name with 'o'.

use mii instead of miibus so we don't drag in all phy support

Add support for the StrataFlash on 2348 boards:
o add bus shim for cfi driver
o add static mapping for CS0 (we map all 16M as the cfi driver doesn't
support demand mapping)

Note this needs some tweaking to work for 2358 boards which is why the
CAMBRIA config is not touched.

Removed duplicate

Merge support for Gateworks Cambria boards:
o add support for IXP435 cpu's (e.g. 64 irq's)
o add support for Cambria-specific devices: npe, led's (front panel and
octal latch), ehci, mcu, ide cf
o redo memory mapping for xscale/ixp4xx boards: previously memory
was assumed aliased to 0x10000000 but this appears to be true only
for ixp425 systems and breaks operation on others; rework so memory
is assumed to start at 0
o rework NPE configuration support to use NPE id's instead of port #'s;
these changes also rename the associated MAC's to follow the NPE's
they are attached to
o update npe firmware to latest rev (same license) and update default fw
imageid's to match; in particular this adds NPE-A and crypto support
o re-style NPE fw handling code and add a console msg identifying the
attributes of the loaded fw
o fix numerous problems with handling failures during npe setup
o fix npe rx q setup; need to spin waiting for mailbox responses during
early boot stages as qmgr interrupts are not delivered; this fixes
the problem where all 8 traffic classifications were not tied to the
rx q (and eliminates the console msg "remember to fix rx q setup")
o add DELAY to npe MII wait logic for IXP435
o strip down builtin phys->virt address translation table in resource
handling to just those resources that require it and add a console msg
to alert people when this (kludge) table needs to be extended
o purge a bunch of dead netbsd-ism's
o cleanup avila led driver
o add Cambria support to boot2 and rework code for better multi-board support

Notes:
1. NPE-A doesn't work and causes NPE-C to stop working; it is disabled
in the hints
2. USB isn't working yet; controller communicates ok but device
discovery fails
3. Cambria support must be configured separately from IXP425 boards;
multi-board support is TBD

Switch to ath hal source code. Note this removes the ath_hal
module; the ath module now brings in the hal support. Kernel
config files are almost backwards compatible; supplying

device ath_hal

gives you the same chip support that the binary hal did but you
must also include

options AH_SUPPORT_AR5416

to enable the extended format descriptors used by 11n parts.
It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.

Add arm/conf/DEFAULTS and populate it with:

options GEOM_BSD
options GEOM_MBR

Remove the first two from all kernel configuration files and
change geom_bsd and geom_mbr from standard to optional.

Minor style nit.

ixp425 parts aren't multicore, so remove the SMP option. They also
don't support the ioapic either, so remove that option too. These
were commented out, but could never be enabled, unlike the other
options in the file that are commented out.

Conform to the options<space><tab> convention everywhere in this file.
This is just a white space change, no functional change.

Multi-bss (aka vap) support for 802.11 devices.

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there

bundled into the wlan module.
