Currently the load address was calculated everytime when it was needed,
and with a mess if clauses. Simplify this by adding a field to struct
ath6kl for each address and choose the address with simple switch
statements.
Also move the code just after target version is retrieved. That way it's
easier to override the values later in the boot process.

When no default board data file is present query the device tree for a
board-id setting to identify the board data to use. If the FDT lacks the
necesary info fall back to the previous behaviour of using a compile-time
board filename.

For now, use a module parameter (ath6kl_p2p) to allow P2P support
to be enabled. This is needed since there is no mechanism for
enabling the P2P mode more dynamically for a single netdev.

Firmware initiates roaming only after it reaches a rssi of 20.
This lower rssi threshold can be modified through a wmi command
to modify the roaming behavior.
kvalo: rename debugfs functions and move comment about rssi units next to
ath6kl_wmi_set_roam_lrssi_cmd()

Firmare sends the logs only when it's internal ring buffer is full. But
if firmware crashes we need to retrieve the latest logs through diagnose
window. This is now done everytime the debugfs file is read.

Just to make them a bit easier to read and unify naming. 32 suffix
in the function name means that it will be a 32 bit transfer. If there's
no number a buffer is transfered instead.
Use void pointers to get rid of ugly casts.
Don't provide target address as a pointer, pass it by value. Same for
the value used in write32().

Firmware sends binary logs with WMIX_DBGLOG_EVENTID event. Create
a buffer which stores the latest logs and which can be copied from
fwlog debugfs file with cp command.
To save memory firmware log support is enabled only when CONFIG_ATH6KL_DEBUG
is enabled.

Probe Request reporting will be needed for P2P and WPS, but some
firmware builds do not seem to like this when P2P is not enabled.
Since we do not yet enable P2P, the safest option here is to just
remove this call for now and bring it back as a more dynamic version
once ath6kl starts advertising support for P2P.

For non-scatter buffers, there is already a bounce buffer which

Last May we started working on cleaning up ath6kl driver which is
currently in staging. The work has happened in a separate
ath6kl-cleanup tree:
http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary
After over 1100 (!) patches we have now reached a state where I would
like to start discussing about pushing the driver to the wireless
trees and replacing the staging driver.
The driver is now a lot smaller and looks like a proper Linux driver.
The size of the driver (measured with simple wc -l) dropped from 49
kLOC to 18 kLOC and the number of the .c and .h files dropped from 107
to 22. Most importantly the number of subdirectories reduced from 26
to zero :)
There are two remaining checkpatch warnings in the driver which we
decided to omit for now:
drivers/net/wireless/ath/ath6kl/debug.c:31:
WARNING: printk() should include KERN_ facility level
drivers/net/wireless/ath/ath6kl/sdio.c:527:
WARNING: msleep < 20ms can sleep for up to 20ms;
see Documentation/timers/timers-howto.txt
The driver has endian annotations for all the hardware specific
structures and there are no sparse errors. Unfortunately I don't have
any big endian hardware to test that right now.
We have been testing the driver both on x86 and arm platforms. The
code is also compiled with sparc and parisc cross compilers.
Notable missing features compared to the current staging driver are:
o HCI over SDIO support
o nl80211 testmode
o firmware logging
o suspend support
Testmode, firmware logging and suspend support will be added soon. HCI
over SDIO support will be more difficult as the HCI driver needs to
share code with the wifi driver. This is something we need to research
more.
Also I want to point out the changes I did for signed endian support.
As I wasn't able to find any support for signed endian annotations I
decided to follow what NTFS has done and added my own. Grep for sle16
and sle32, especially from wmi.h.
Various people have been working on the cleanup, the hall of
fame based on number of patches is:
