+TODO:
+
+We are working hard on cleaning up the driver. There's sooooooooo much todo
+so instead of editing this file please use the wiki:
+
+http://wireless.kernel.org/en/users/Drivers/ath6kl
+
+There's a respective TODO page there. Please also subscribe to the wiki page
+to get e-mail updates on changes.
+
+IRC:
+
+We *really* need to coordinate development for ath6kl as the cleanup
+patches will break pretty much any other patches. Please use IRC to
+help coordinate better:

+     * During normal bootup, small reads may be required.
+     * Rather than issue an HIF Read and then wait as the Target
+     * adds successive bytes to the FIFO, we wait here until
+     * we know that response data is available.
+     *
+     * This allows us to cleanly timeout on an unexpected
+     * Target failure rather than risk problems at the HIF level.  In
+     * particular, this avoids SDIO timeouts and possibly garbage
+     * data on some host controllers.  And on an interconnect
+     * such as Compact Flash (as well as some SDIO masters) which
+     * does not provide any indication on data timeout, it avoids
+     * a potential hang or garbage response.
+     *
+     * Synchronization is more difficult for reads larger than the
+     * size of the MBOX FIFO (128B), because the Target is unable
+     * to push the 129th byte of data until AFTER the Host posts an
+     * HIF Read and removes some FIFO data.  So for large reads the
+     * Host proceeds to post an HIF Read BEFORE all the data is
+     * actually available to read.  Fortunately, large BMI reads do
+     * not occur in practice -- they're supported for debug/development.
+     *
+     * So Host/Target BMI synchronization is divided into these cases:
+     *  CASE 1: length < 4
+     *        Should not happen
+     *
+     *  CASE 2: 4 <= length <= 128
+     *        Wait for first 4 bytes to be in FIFO
+     *        If CONSERVATIVE_BMI_READ is enabled, also wait for
+     *        a BMI command credit, which indicates that the ENTIRE
+     *        response is available in the the FIFO
+     *
+     *  CASE 3: length > 128
+     *        Wait for the first 4 bytes to be in FIFO
+     *
+     * For most uses, a small timeout should be sufficient and we will
+     * usually see a response quickly; but there may be some unusual
+     * (debug) cases of BMI_EXECUTE where we want an larger timeout.
+     * For now, we use an unbounded busy loop while waiting for
+     * BMI_EXECUTE.
+     *
+     * If BMI_EXECUTE ever needs to support longer-latency execution,
+     * especially in production, this code needs to be enhanced to sleep
+     * and yield.  Also note that BMI_COMMUNICATION_TIMEOUT is currently

+ *
+ * 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
+ * 1 buffer - 1024 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

+/* Debug support on a per-module basis
+ *
+ * Usage:
+ *
+ *   Each module can utilize it's own debug mask variable.  A set of commonly used
+ *   masks are provided (ERRORS, WARNINGS, TRACE etc..).  It is up to each module
+ *   to define module-specific masks using the macros above.
+ *
+ *   Each module defines a single debug mask variable debug_XXX where the "name" of the module is
+ *   common to all C-files within that module.  This requires every C-file that includes a_debug.h
+ *   to define the module name in that file.
+ *
+ *   Example:
+ *
+ *   #define ATH_MODULE_NAME htc
+ *   #include "a_debug.h"
+ *
+ *   This will define a debug mask structure called debug_htc and all debug macros will reference this
+ *   variable.
+ *
+ *   A module can define module-specific bit masks using the ATH_DEBUG_MAKE_MODULE_MASK() macro:
+ *
+ *      #define ATH_DEBUG_MY_MASK1  ATH_DEBUG_MAKE_MODULE_MASK(0)
+ *      #define ATH_DEBUG_MY_MASK2  ATH_DEBUG_MAKE_MODULE_MASK(1)
+ *
+ *   The instantiation of the debug structure should be made by the module.  When a module is
+ *   instantiated, the module can set a description string, a default mask and an array of description
+ *   entries containing information on each module-defined debug mask.
+ *   NOTE: The instantiation is statically allocated, only one instance can exist per module.
+ *
+ *   Example:
+ *
+ *
+ *   #define ATH_DEBUG_BMI  ATH_DEBUG_MAKE_MODULE_MASK(0)
+ *
+ *   #ifdef DEBUG
+ *   static struct ath_debug_mask_description bmi_debug_desc[] = {
+ *       { ATH_DEBUG_BMI , "BMI Tracing"},   <== description of the module specific mask
+ *   };
+ *
+ *   ATH_DEBUG_INSTANTIATE_MODULE_VAR(bmi,
+ *                                    "bmi"  <== module name
+ *                                    "Boot Manager Interface",  <== description of module
+ *                                    ATH_DEBUG_MASK_DEFAULTS,          <== defaults
+ *                                    ATH_DEBUG_DESCRIPTION_COUNT(bmi_debug_desc),
+ *                                    bmi_debug_desc);
+ *
+ *   #endif
+ *
+ *  A module can optionally register it's debug module information in order for other tools to change the
+ *  bit mask at runtime.  A module can call  A_REGISTER_MODULE_DEBUG_INFO() in it's module
+ *  init code.  This macro can be called multiple times without consequence.  The debug info maintains
+ *  state to indicate whether the information was previously registered.

+ * 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
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR6K Counter #4.  As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

+ *          otherwise it can call the function pointer to check pending events.
+ *

+ *   input : none
+ *   output : HIF_DEVICE_IRQ_PROCESSING_MODE (interrupt processing mode)
+ *   note: the hif layer interfaces with the underlying OS-specific bus driver. The HIF

+ *   input :
+ *   output : HIF_MASK_UNMASK_RECV_EVENT function pointer
+ *   notes: this is optional for the HIF layer.  The HIF layer may require a special mechanism
+ *          to mask receive message events.  The upper layer can call this pointer when it needs
+ *          to mask/unmask receive events (in case it runs out of buffers).
+ *
+ *   HIF_DEVICE_POWER_STATE_CHANGE
+ *
+ *   input : HIF_DEVICE_POWER_CHANGE_TYPE
+ *   output : none
+ *   note: this is optional for the HIF layer.  The HIF layer can handle power on/off state change

+ *         The caller must guarantee that no HIF read/write requests will be made after the device

+ * 
+ *   input : none
+ *   output : struct hif_device_irq_yield_params
+ *   note: This query checks if the HIF layer wishes to impose a processing yield count for the DSR handler.
+ *   The DSR callback handler will exit after a fixed number of RX packets or events are processed.  
+ *   This query is only made if the device reports an IRQ processing mode of HIF_DEVICE_IRQ_SYNC_ONLY. 
+ *   The HIF implementation can ignore this command if it does not desire the DSR callback to yield.
+ *   The HIF layer can indicate the maximum number of IRQ processing units (RX packets) before the
+ *   DSR handler callback must yield and return control back to the HIF layer.  When a yield limit is 
+ *   used the DSR callback will not call HIFAckInterrupts() as it would normally do before returning.  
+ *   The HIF implementation that requires a yield count must call HIFAckInterrupt() when it is prepared
+ *   to process interrupts again.
+ *   
+ *   HIF_CONFIGURE_QUERY_SCATTER_REQUEST_SUPPORT
+ *   input : none
+ *   output : struct hif_device_scatter_support_info
+ *   note:  This query checks if the HIF layer implements the SCATTER request interface.  Scatter requests
+ *   allows upper layers to submit mailbox I/O operations using a list of buffers.  This is useful for
+ *   multi-message transfers that can better utilize the bus interconnect.
+ * 
+ * 
+ *   HIF_DEVICE_GET_OS_DEVICE
+ *   intput : none
+ *   output : struct hif_device_os_device_info;
