good luck.
config AR6000_WLAN_DEBUG
bool "Enable retrieval of firmware debugging information"
depends on AR6000_WLAN
default n
help
The AR6k firmware maintains a log of debugging events that
gets flushed to the host on various occasions. Retrieval of
this data is very slow, taking several seconds.
If in doubt, say N.
config AR6000_WLAN_RESET
bool "Soft-reset when shutting down"
depends on AR6000_WLAN
default n
help
The AR6k module can be explicitly reset when shutting down
the device. This adds a delay of about two seconds to suspend,
module removal, and so on. Since the WLAN SDIO function is
generally disabled soon thereafter anyway, this reset seems
superfluous.
If in doubt, say N.

Although we had envisioned BMI to run on top of HTC, this is not what the
final implementation boiled down to on dragon. Its a part of BSP and does
not use the HTC protocol either. On the host side, however, we were still
living with the original idea. I think the time has come to accept the truth
and separate it from HTC which has been carrying BMI's burden all this while.
It shall make HTC state machine relatively simpler

* KNOWN BUGS:

*/
/*
* Differences from Atheros' HIFs:
*
* - synchronous and asynchronous requests may get reordered with respect to
* each other, e.g., if HIFReadWrite returns for an asynchronous request and
* then HIFReadWrite is called for a synchronous request, the synchronous
* request may be executed before the asynchronous request.
*
* - request queue locking seems unnecessarily complex in the Atheros HIFs.
*
* - Atheros mask interrupts by calling sdio_claim_irq/sdio_release_irq, which
* can cause quite a bit of overhead. This HIF has its own light-weight
* interrupt masking.
*
* - Atheros call deviceInsertedHandler from a thread spawned off the probe or
* device insertion function. The original explanation for the Atheros SDIO
* stack said that this is done because a delay is needed to let the chip
* complete initialization. There is indeed a one second delay in the thread.
*
* The Atheros Linux SDIO HIF removes the delay and only retains the thread.
* Experimentally removing the thread didn't show any conflicts, so let's get
* rid of it for good.
*
* - The Atheros SDIO stack with Samuel's driver sets SDIO_CCCR_POWER in
* SDIO_POWER_EMPC. Atheros' Linux SDIO code apparently doesn't. We don't
* either, and this seems to work fine.
* @@@ Need to check this with Atheros.

* mmc_remove_host ..> sdio_bus_remove -> sdio_ar6000_remove ->
* ar6000_deactivate -> ar6000_do_deactivate ->
* deviceRemovedHandler (HTCTargetRemovedHandler) -> HIFShutDownDevice
*
* This is roughly the same sequence as suspend, described below.
*
* Module removal:
*
* sys_delete_module -> ar6000_cleanup_module -> HTCShutDown ->
* HIFShutDownDevice -> sdio_unregister_driver ...> sdio_bus_remove ->
* sdio_ar6000_remove -> ar6000_deactivate -> ar6000_do_deactivate
*
* In this case, HIFShutDownDevice must call sdio_unregister_driver to
* notify the driver about its removal. ar6000_do_deactivate must not call
* deviceRemovedHandler, because that would loop back into HIFShutDownDevice.
*
* Suspend:
*
* device_suspend ...> s3cmci_suspend ...> sdio_bus_remove ->
* sdio_ar6000_remove -> ar6000_deactivate -> ar6000_do_deactivate ->
* deviceRemovedHandler (HTCTargetRemovedHandler) -> HIFShutDownDevice
*
* We must call deviceRemovedHandler to inform the ar6k stack that the device
* has been removed. Since HTCTargetRemovedHandler calls back into
* HIFShutDownDevice, we must also prevent the call to
* sdio_unregister_driver, or we'd end up recursing into the SDIO stack,
* eventually deadlocking somewhere.
*
* rfkill:
*
* rfkill_state_store -> rfkill_toggle_radio -> gta02_wlan_toggle_radio ->
* ar6000_rfkill_cb -> ar6000_deactivate -> ar6000_do_deactivate ->
* deviceRemovedHandler (HTCTargetRemovedHandler) -> HIFShutDownDevice
*
* This is similar to suspend - only the entry point changes.

*
* the unit test has the following constraints:
*
* The target has at least 8 buffers of 256 bytes each. The host will send
* the following pattern of buffers in rapid succession :
*
* 1 buffer - 128 bytes
* 1 buffer - 256 bytes
* 1 buffer - 512 bytes

*
* The host will send the buffers to one mailbox and wait for buffers to be reflected
* back from the same mailbox. The target sends the buffers FIFO order.
* Once the final buffer has been received for a mailbox, the next mailbox is tested.
*
*
* Note: To simplifythe test , we assume that the chosen buffer sizes
* will fall on a nice block pad
*
* It is expected that higher-order tests will be written to stress the mailboxes using
* a message-based protocol (with some performance timming) that can create more

/*
* Bootloader Messaging Interface (BMI)
*
* BMI is a very simple messaging interface used during initialization
* to read memory, write memory, execute code, and to define an
* application entry PC.
*
* It is used to download an application to AR6K, to provide
* patches to code that is already resident on AR6K, and generally
* to examine and modify state. The Host has an opportunity to use
* BMI only once during bootup. Once the Host issues a BMI_DONE
* command, this opportunity ends.
*
* The Host writes BMI requests to mailbox0, and reads BMI responses
* from mailbox0. BMI requests all begin with a command
* (see below for specific commands), and are followed by

* iPAQ H1940 touchscreen support
*
* ChangeLog
*
* 2004-09-05: Herbert Pötzl <herbert@13thfloor.at>
* - added clock (de-)allocation code
*
* 2005-03-06: Arnaud Patard <arnaud.patard@rtp-net.org>
* - h1940_ -> s3c2410 (this driver is now also used on the n30
* machines :P)
* - Debug messages are now enabled with the config option
* TOUCHSCREEN_S3C2410_DEBUG
* - Changed the way the value are read
* - Input subsystem should now work
* - Use ioremap and readl/writel
*
* 2005-03-23: Arnaud Patard <arnaud.patard@rtp-net.org>
* - Make use of some undocumented features of the touchscreen
* controller
*
* 2007-05-23: Harald Welte <laforge@openmoko.org>
* - Add proper support for S32440
*
* 2008-06-23: Andy Green <andy@openmoko.com>
* - removed averaging system
* - added generic Touchscreen filter stuff
*
* 2008-11-27: Nelson Castillo <arhuaco@freaks-unidos.net>
* - improve interrupt handling

* - We choose the set with more elements. If more than "threshold"

* to define the valid range for this dimension [min, max], otherwise we
* discard all the points and go to step 1.
*
* 3) We consider the unsorted S samples and try to feed them to the next
* filter in the chain. If one of the points of each sample
* is not in the allowed range for its dimension, we discard the sample.
