Michael Buesch 403a3a1361 b43: Add fw capabilities
Add automagic feature flags, so the firmware can tell the driver
about supported features and the driver can switch features on/off as
needed.

Michael Buesch 060210f938 b43: Dynamically control log verbosity
Dynamically control the log verbosity with a module parameter.
This enables us to dynamically enable debugging messages (or disable
info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose.

This increases the module size by about 3k. But in practice it reduces the
module size for the user, because some distributions ship the b43 module
with CONFIG_B43_DEBUG set, which increases the module by about 15k.

So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG.
There is no reason to keep it in a production-release kernel.
So we have a net reduction in size by about 12k.

This patch also adds a printk of the wireless core revision, so people
don't have to enable SSB debugging to get the wireless core revision.

Michael Buesch 1a9f509368 b43: Automatically probe for opensource firmware
First probe for proprietary firmware and then probe for opensource firmware.
This way around it's a win-win situation.
1) If proprietary fw is available, it will work.
2) If opensource firmware is available, but no proprietary (Distros can only ship open fw)
   it might work.
3) If both open and proprietary are available, it will work, because it selects
   the proprietary. We currently don't prefer the open fw in this case, because it doesn't
   work on all devices. It would introduce a regression otherwise.

The remaining FIXMEs in this patch are harmless, because they only matter on multiband
devices, which are not implemented yet anyway.

This adds debugfs files for random SHM access.
This is needed in order to implement firmware and driver debugging
scripts in userspace.

Michael Buesch f5eda47f45 b43: Rewrite LO calibration algorithm
This patch distributes the Local Oscillator calibration bursts over time,
so that calibration only happens when it's actually needed.
Currently we periodically perform a recalibration of the whole table.
The table is huge and this takes lots of time. Additionally only small bits
of the table are actually needed at a given time. So instead of maintaining
a huge table with all possible calibration values, we create dynamic calibration
settings that
a) We only calibrate when they are actually needed.
b) Are cached for some time until they expire.
So a recalibration might happen if we need a calibration setting that's not
cached, or if the active calibration setting expires.
Currently the expire timeout is set to 30 seconds. We may raise that in future.

This patch reduces overall memory consumption by nuking the
huge static calibration tables.

This patch has been tested on several 4306, 4311 and 4318 flavours.

Michael Buesch d987160b71 b43: Fix rxheader channel parsing
This patch fixes the parsing of the RX data header channel field.

The current code parses the header incorrectly and passes a wrong
channel number and frequency for each frame to mac80211.
The FIXMEs added by this patch don't matter for now as the code
where they live won't get executed anyway. They will be fixed later.
