The initvals.h file is over 7000 lines now, so instead of adding
AR9003 initvals to it instead lets split the current initvals.h by
hardware family: AR5008, AR9001, AR9002
The AR9003 family will have its own initval file later.

The AR9003 family requires a change on the loop and can also skip
testing the PHY timing registers. This chip test can now be used
by all Atheros hardware families, including legacy. We can
eventually move this out to the generic ath module.

ANI is still being debugged on AR9003 by our systems team
so it should not yet be enabled yet. When ANI will be
enabled all ANI functionality is expected to be enabled
so fill the ANI functionality to all for AR9003 for now
as well.

The PHY split is easier done in a few steps. First move
the RF ops to the private ops and rename them accordingly.
We split PHY stuff up first for the AR5008 and AR9002
families. There are some callbacks that AR9002 share
with the AR5008 familiy so we set those first, if AR9002
has some different callbacks it will override them upon
hardware init.

This is used only once by ath9k_hw_process_ini() to
write an array of phy registers through REG_WRITE_ARRAY(),
but we already call REG_WRITE_ARRAY() multiple times
on the same caller so just remove this pointless wrapper.
We'll eventually just move the ath9k_hw_process_ini()
caller as an callback to abstract away between different
hardware families.
Although this change is subtle I should note that this
does change the delay pattern on writing the next series
of registers. REG_WRITE_ARRAY() uses a counter for each
register write and does a udelay(1) every 64 writes. By
removing this call it means that the counter is processed
for all the iniBB_RfGain registers and is incremented
on ath9k_hw_process_ini(), before this the after the call
ath9k_hw_write_regs() was made the register counter was
kept at the same index number prior to the call.

ath9k supports the AR5008, AR9001 and AR9002 family of Atheros
chipsets, all 802.11n. The new breed of 802.11n chips, the
AR9003 family will be supported as well soon. To help with its
support we're going to add a few callbacks for hardware routines
which differ considerably instead of adding branch checks for
the revision at runtime.

wl1251 is embedded chip that can be connected using SDIO bus, and is not
an actual SDIO card. For this reason there is a need to pass some board
specific data, like 'EEPROM is attached' flag or power control callback.
However currently there is no way to pass this data through SDIO subsystem,
so this patch registers dummy platform_device to allow that, until we
have a better solution to this.

rt2800pci used the callback write_tx_desc to write the tx descriptor but
also to update the txwi which is part of the dma mapped skb. Since the
memory was already DMA mapped _before_ the call to write_tx_desc the
device didn't get the txwi data at all or only sporadically.
The call order is basically as follows (from rt2x00queue.c):
1) write_tx_data
2) rt2x00queue_map_txskb
3) write_tx_desc
Hence, we shouldn't touch the skb in write_tx_desc anymore.
To fix this issue create a new rt2800pci_write_tx_data callback and use it
for updating the txwi _before_ the memory gets DMA mapped.
The tx descriptor is still written (as before) in write_tx_desc.
This patch allows basic TX on an rt305x soc device but I'm pretty sure
that it will fix pci based cards as well. I can associate just fine with
an AP now but I wasn't able to get a wpa secured connection working yet.

event body
In a scenario, where a cfg80211 driver (station mode) does not send assoc request
and assoc response IEs in cfg80211_connect_result after a successful association
to an AP, cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE to the user space
application with NULL data. This can cause an issue at the event recipient.
An example of this is when cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE
events with NULL event body to wpa_supplicant. The wpa_supplicant overwrites
the assoc request and assoc response IEs for this station with NULL data.
If the association is WPA/WPA2, the wpa_supplicant is not able to generate
EAPOL handshake messages, since the IEs are NULL.
With the patch, req_ie and resp_ie will be NULL by avoiding the
assignment if the driver has not sent the IEs to cfg80211. The event sending
code sends the events only if resp_ie and req_ie are not NULL. This
will ensure that the events are not sent with NULL event body.

usb device
This patch fixes two warnings below after unplugging ar9271 usb device:
-one is a kernel warning[1]
-another is a lockdep warning[2]
The root reason is that __skb_queue_purge can't be executed in hardirq
context, so the patch forks ath9k_skb_queue_purge(ath9k version of _skb_queue_purge),
which frees skb with dev_kfree_skb_any which can be run in hardirq
context safely, then prevent the lockdep warning and kernel warning after
unplugging ar9271 usb device.

In ath9k-htc register out path, ath9k-htc will pass skb->data into
usb hcd and usb hcd will do dma mapping and unmapping to the buffer
pointed by skb->data, so we should pass a cache-line aligned address.
This patch replace __dev_alloc_skb with alloc_skb to make skb->data
pointed to a cacheline aligned address simply since ath9k-htc does not
skb_push on the skb and pass it to mac80211, also use kfree_skb to free
the skb allocated by alloc_skb(we can use kfree_skb safely in hardirq
context since skb->destructor is NULL always in the path).
