Split the ATH6KL firmware files to a different recipe and package so
they can be used regardless of what driver we are using (the external
module or the upstream driver).
Reuse the 'firmware-atheros' recipe which was creating a package with
bluetooth firmware, to create the package with wireless firmware as
well.
Also remove 'ccimx6' as compatible machine for the external atheros
module, as the module does not even compile with the kernel version we
are using (3.14).

This is a regression introduced in a74363c. The MOD_VARIANT variable was
not correctly set because in kernel 2.6.35 there is no device-tree
support.
The fix is to get the module variant from the sysfs as a fallback for
old kernels.

Some CC6 variants have wireless but not bluetooth. Those variants need a

A post-down script was unloading the Atheros wireless driver
when the network interfaces were brought down.
On rare occasions the 'rmmod' command was not able to complete
and may leave the system in an unexpected state.
This patch removes the post-down script for the ccardimx28 platform
and leaves it only for the ccimx6 platform, where the unloading
is wanted to reset the driver after suspend.

By removing the driver on ifdown and loading it on ifup we workaround some

Version v3.4p6 seems to have some problems with WEP encription. Version
v3.4p4 seems to work better with WEP, so revert to that version.

There seems to be a race condition in the load of the 'cfg80211' and
'ath6kl_sdio' modules. If we try to load the atheros module before the
cfg80211 is settled down, the driver crash.
The workaround is just separate the load of both modules in two separate
'modprobe' commands and add a small delay between them.

The wireless module occasionally fails to load in kernel v3.10.
If that is the case, unload the driver and load it again (up to
five retries).
Notes:
- Only the ath6kl_sdio module needs to be unloaded and reloaded.
- The chip is not issued a power cycle via CHIP_PWD_L because
this demonstrated to cause failure, instead of improving
behaviour.
- The 2-seconds sleep after unloading the driver is a security
measure to avoid other problems seen during test cycle.

In Linux 2.6.35, the kernel module accepting the parameters on load
was 'ath6kl_sdio' while in 3.10 is 'ath6kl_core'.
So we need to apply the load parameters to either module depending on
the kernel version.
This is solved by configuring the modprobe configuration file
'/etc/modprobe.d/atheros.conf' with the parameters to the correct
module instead of passing them in the command line.

With the old version of the kernel (2.6.35) we build an external atheros
kernel module, while with the new kernel (3.10) the atheros driver is
included with the kernel sources.
However, the new driver needs the firmware files and the driver load
scripts that are stored with the old driver.
So put a dependence on kernel-module-atheros regardless of the kernel
version and then rework the kernel-module-atheros recipe to build the
whole driver for the old kernel or only the firmware for the new kernel.
