+#
+# Extended Make invocation:
+#
+# make ATH_BUILD_TYPE=<build type> ATH_SDIO_STACK_BASE=<sdio stack install path> (all | clean | clobber)
+#
+# Notes:
+# 1. This makefile must be invoked from the host/ directory
+# 2. The <build type> must match an entry in localmake.linux.inc.
+# 3. The localmake.linux.inc can be overridden using an include file outside the build tree.
+# This file (name and path) can be set via the ATH_MAKE_INCLUDE_OVERRIDE variable.
+# ** If ATH_MAKE_INCLUDE_OVERRIDE is used, you can define all build variables in that file
+# instead of using command line arguments **. This feature is provided for developers
+# that may want to customize the build using a single include file.
+#
+# For example :
+#
+# " make ATH_MAKE_INCLUDE_OVERRIDE=$HOME/mymake.inc "
+#
+# could be used, as long as "mymake.inc" defines all the required variables (see below)
+#
+# Required Variables:
+#
+# ATH_OS_SUB_TYPE - on linux, this must be "linux_2_4" for 2.4 kernels or left blank for 2.6 kernels.
+# ATH_LINUXPATH - linux kernel source path
+# ATH_CROSS_COMPILE_TYPE - optional cross compiler path , leave blank for local gcc compilation
+# ATH_ARCH_CPU_TYPE - CPU architecture type, leave blank for local gcc compilation
+# ATH_SDIO_STACK_BASE - SDIO Stack installation path to compile the SDIO HIF layer against an externally supplied
+# SDIO stack source.
+#
+# Override variables:
+#
+# ATH_MAKE_INCLUDE_OVERRIDE - full path to include file which overrides the default (localmake.linux.inc)
+# this file can contain other overrides specific to a developers
+# workspace environment.

+Sections
+A) Code Organization
+B) Building the code and loading the Driver
+
+A) Code organization
+
+The host side code for different platforms is organized as follows:
+1) os: Captures the os specific dependencies. The network adaptor driver is implemented in this directory.
+2) wmi: Implements the wireless module interface.
+3) htc: Implements the host transport communication interface.
+4) hif: Implements the host interconnect framework for different interfaces.
+6) tools: Contains the implementation for several tools used to interact with the wlan driver.
+7) wlan: Implements some utility functions related to the core wireless lan.
+8) sdiostack: Contains the sources for the SDIO/SPI stack.
+9) bmi: Implements the bootloader messaging interface.
+10) support: Contains scripts to load the driver and control some aspects of the wlan device using the tools present in the tools directory.

+B) Building the code
+ -----------------
+ cd into the top-level directory of the distribution
+ Set environment variables (also see host/localmake.linux.inc):
+ export WORKAREA=`pwd` [Note: Use backticks, not quote marks]
+ export ATH_BUILD_TYPE=LOCAL_i686
+ export ATH_LINUXPATH=/usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9 [Note: This is an example]
+ export ATH_BUS_TYPE=SDIO
+ export ATH_HC_DRIVERS=pci_std/
+ export ATH_PLATFORM=$ATH_BUILD_TYPE-$ATH_BUS_TYPE
+
+ Build device driver and support tools:
+ make -C host
+
+ Load the wireless driver on your system:
+ host/support/loadAR6000.sh
+
+ Configure the wireless network interface with ifconfig and iwconfig.
+ For example:
+ ifconfig eth1 192.168.1.99 up
+ iwconfig eth1 essid "MyAccessPointSSID"

+/* This is a mailbox hardware unit test that must be called in a schedulable context
+ * This test is very simple, it will send a list of buffers with a counting pattern
+ * and the target will invert the data and send the message back
+ *
+ * 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
+ * a message-based protocol (with some performance timming) that can create more
+ * randomness in the packets sent over mailboxes.

+ * 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).
+ *

+Boot the system, log in and switch to

+Load the modules using

+You should get a few messages, like the major number displayed.
+To debug messages use:
+#dmesg
+You'll get lots of debug, with our stuff at the end. You can use this at anytime.
+To force a card inseration, you can use the test application.
+This will send IOCTL to the local bus driver telling it to announce the arrival of a certain card.
+The bus driver will then look for a function driver and find sdio_generic_functiom has refistered for this card.
+The bus driver will call the function drivers probe. This function will acept the card.
+#bdtest -i
+
+Do a dmesg and you'll see what went on.
+
+This should give you enough to excercise the infrastructure.

+# Notes:
+# 1. This makefile must be invoked from the host/ directory

+# 3. The localmake.$(CT_OS_TYPE).inc can be overridden using an include file outside the build tree.
+# This file (name and path) can be set via the CT_MAKE_INCLUDE_OVERRIDE variable.
+# ** If CT_MAKE_INCLUDE_OVERRIDE is used, you can define all build variables in that file
+# instead of using command line arguments **. This feature is provided for developers

+# For example :
+#
+# " make CT_MAKE_INCLUDE_OVERRIDE=$HOME/mymake.inc "

+# CT_BUILD_TYPE - build type defined in localmake.linux.inc, this variable is also used
+# to build a path to hold compiled binaries.
+# CT_OS_TYPE - operating system type (linux, etc...)
+# CT_OS_SUB_TYPE - on linux, this must be "linux_2_4" for 2.4 kernels or left blank for 2.6 kernels.
+# CT_LINUXPATH - linux kernel source path
+# CT_CROSS_COMPILE_TYPE - optional cross compiler path
+# CT_ARCH_CPU_TYPE - CPU architecture type
+#
+# One of the following should be used to build the tree:
+# ALL_BUILD=1 - build all source code
+# HDK_BUILD=1 - build only HCD and sample function drivers
+# PDK_BUILD=1 - build only the sample function drivers
+# BUS_BUILD=1 - build bus driver, library and HCDs for use with built-in SDIO cards.

+ * A request marked as PSEUDO is synchronized with bus requests and is not a true request

+ * A request marked with a BARRIER flag requires that the completion routine be called
+ * before the next bus request starts. This is required for HCD requests that can change
+ * bus or clock modes. Changing the clock or bus mode while a bus request is pending
+ * can cause problems.

+ @notes:
+ The bus driver maintains an internal queue of SDREQUEST structures submited by function
+ drivers. The driver should use request macros to obtain a pointer to the current SDREQUEST
+ at the head of the queue. The driver can access the fields of the current request in order
+ to program hardware appropriately. Once the request completes, the driver should update
+ the current request information (final status, response bytes and/or data) and call
+ SDIO_HandleHcdEvent() with the event type of EVENT_HCD_TRANSFER_DONE.

+ request.

+ data structure to pass the required current in mA. Slot current allocation
+ is not cummulative and this command should only be issued once by each function

+ The command returns SDIO_STATUS_NO_RESOURCES if the

+ contain the remaining current available to the slot. The slot current should
+ be allocated before the function is enabled using SDCONFIG_FUNC_ENABLE_DISABLE.
+ When a function driver is unloaded it should free the slot current allocation
+ by using the SDCONFIG_FUNC_FREE_SLOT_CURRENT command.

+ and pass the value in the SDCONFIG_BUS_MODE_DATA structure.
+ If the bus width is changed (1 or 4 bit) the caller must adjust the mode flags
+ for the new width. Cards cannot be switched between 1/4 bit and SPI mode.
+ Switching to or from SPI mode requires a power cycle. Adjustments to the clock
+ rate is immediate on the next bus transaction. The actual clock rate value is
+ limited by the host controller and is reported in the ClockRate field when the
+ command completes successfully.
+ The bus mode change is card wide and may affect other SDIO functions on
+ multi-function cards. Use this feature with caution. This feature should NOT be
+ used to dynamically control clock rates during runtime and should only be used
+ at card initialization. Changing the bus mode must be done with SDIO function
+ interrupts masked.
+ This request can block and must only be called from a schedulable context.
+
+ @example: Example of changing the clock rate:
+ SDCONFIG_BUS_MODE_DATA busSettings;
