Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.
This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.
On MIPS this reduces the total size for the modules by about 20k.

This initial DFS module provides basic functionality to deal
with radar pulses reported by the Atheros DFS HW pulse detector.
The reported data is evaluated and basic plausibility checks
are performed to filter false pulses. Passing radar pulses are
forwarded to pattern detectors which are not yet implemented.
(Some modifications to actually use ATH9K_DFS_DEBUGFS based on comments
from Julian Calaby <julian.calaby@gmail.com>. -- JWL)

Most ath9k devices are PCI/PCIe based, therefor making PCI/PCIe support
default y helps those porting a config from 2.6 kernel series
from getting "non-functional" wireless drivers with 3.x kernel series.

We make oldconfig every time when a new kernel arrives, but
if we don't have such a device(I guess this is the most common
case for a new device), the default value should be 'n' so
that the kernel size we build doesn't grow up too much quickly.
For anyone who has the device, it is OK for them to turn it on
by themselves.

Currently ath9k only available in menuconfig if PCI bus
support is enabled. However the driver is required for
the built-in wireless MACs of the Atheros AR9130/AR9132
SoCs. These SoCs have no PCI controller, the wireless
MAC is connected to the AHB bus on them.
Introduce separated config options for the supported
buses, in order to allow building of ath9h without PCI
bus support.
As a bonus, this patch removes the cross-reference of
the ATHEROS_AR71XX option which is not present in the
kernel.

In my setups, ath9k's debugfs files are most of the time much more
useful than the messages generated by enabling CONFIG_ATH_DEBUG along
with the right debug flags.
Since CONFIG_ATH_DEBUG comes with a noticeable overhead on embedded
systems, this patch makes it possible to use the debugfs files without
that option.

ath9k and ath9k_htc share a lot of common hardware characteristics.
They only differ in that ath9k_htc works with a target CPU and ath9k
works directly with the hardware. ath9k_htc will do *some* things in
the firmware, but a lot of others on the host.
The common 802.11n hardware code is already shared through the ath9k_hw
module. Common helpers amongst all Atheros drivers can use the ath module,
this includes ath5k and ar9170 as users. But there is some common driver
specific helpers which are not exactly hardware code which ath9k and
ath9k_htc can share. We'll be using ath9k_common for this to avoid
bloating the ath module and the common 802.11n hardware module ath9k_hw.
We start by sharing skb pre and post processing in preparation for a hand
off to mac80211.

hw code for Atheros 802.11n hardware is commmon between
different chipsets. This moves this code into a separate
module, the next expected user of this code will be
the ath9k_htc module.
The ath9k/ dir is now selected by ATH9K_HW, an option which
gets selected by either ath9k or ath9k_htc, but remains
invisible for user menuconfig configuration. If either
ath9k or ath9k_htc will be compiled into the kernel
ath9k_hw will also be compiled in.

ath9k uses this for now, ath9k_htc is expected to re-use this
as well. We lave ath5k as is, but it certainly can also be
converted later.
The ath9k module parameter and debugfs entry is kept.

ath9k supports the AR9002 family of chipsets. This includes
the AR9285 and the miniPCI AR9223 and AR9220 (which themselves
have AR9280+AR5133).
We now refer people to the wiki page as it seems this is not
as popular as we would have hoped.

This ports the ath9k rfkill code to the new API offered by
cfg80211 and thus removes a lot of useless stuff.
