-
-	  This is a driver for the Atheros "otus" 802.11n USB devices.
-
-	  These devices require additional firmware (2 files).
-	  For now, these files can be downloaded from here:

-	  If you choose to build a module, it'll be called ar9170usb.

 /**
- * BSM (Bootstrap State Machine)
- *
- * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
- * in special SRAM that does not power down when the embedded control
- * processor is sleeping (e.g. for periodic power-saving shutdowns of radio).
- *
- * When powering back up after sleeps (or during initial uCode load), the BSM
- * internally loads the short bootstrap program from the special SRAM into the
- * embedded processor's instruction SRAM, and starts the processor so it runs
- * the bootstrap program.
- *
- * This bootstrap program loads (via PCI busmaster DMA) instructions and data
- * images for a uCode program from host DRAM locations.  The host driver
- * indicates DRAM locations and sizes for instruction and data images via the
- * four BSM_DRAM_* registers.  Once the bootstrap program loads the new program,
- * the new program starts automatically.
- *
- * The uCode used for open-source drivers includes two programs:
- *
- * 1)  Initialization -- performs hardware calibration and sets up some
- *     internal data, then notifies host via "initialize alive" notification
- *     (struct iwl_init_alive_resp) that it has completed all of its work.
- *     After signal from host, it then loads and starts the runtime program.
- *     The initialization program must be used when initially setting up the
- *     NIC after loading the driver.
- *
- * 2)  Runtime/Protocol -- performs all normal runtime operations.  This
- *     notifies host via "alive" notification (struct iwl_alive_resp) that it
- *     is ready to be used.
- *
- * When initializing the NIC, the host driver does the following procedure:
- *
- * 1)  Load bootstrap program (instructions only, no data image for bootstrap)
- *     into bootstrap memory.  Use dword writes starting at BSM_SRAM_LOWER_BOUND
- *
- * 2)  Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction
- *     images in host DRAM.
- *
- * 3)  Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked:
- *     BSM_WR_MEM_SRC_REG = 0
- *     BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND
- *     BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image
- *
- * 4)  Load bootstrap into instruction SRAM:
- *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START
- *
- * 5)  Wait for load completion:
- *     Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0
- *
- * 6)  Enable future boot loads whenever NIC's power management triggers it:
- *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN
- *
- * 7)  Start the NIC by removing all reset bits:
- *     CSR_RESET = 0
- *
- *     The bootstrap uCode (already in instruction SRAM) loads initialization
- *     uCode.  Initialization uCode performs data initialization, sends
- *     "initialize alive" notification to host, and waits for a signal from
- *     host to load runtime code.
- *
- * 4)  Point (via BSM_DRAM_*) to the "runtime" uCode data and instruction
- *     images in host DRAM.  The last register loaded must be the instruction
- *     byte count register ("1" in MSbit tells initialization uCode to load
- *     the runtime uCode):
- *     BSM_DRAM_INST_BYTECOUNT_REG = byte count | BSM_DRAM_INST_LOAD
- *
- * 5)  Wait for "alive" notification, then issue normal runtime commands.
- *
- * Data caching during power-downs:
- *
- * Just before the embedded controller powers down (e.g for automatic
- * power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA)
- * a current snapshot of the embedded processor's data SRAM into host DRAM.
- * This caches the data while the embedded processor's memory is powered down.
- * Location and size are controlled by BSM_DRAM_DATA_* registers.
- *
- * NOTE:  Instruction SRAM does not need to be saved, since that doesn't
- *        change during operation; the original image (from uCode distribution
- *        file) can be used for reload.
- *
- * When powering back up, the BSM loads the bootstrap program.  Bootstrap looks
- * at the BSM_DRAM_* registers, which now point to the runtime instruction
- * image and the cached (modified) runtime data (*not* the initialization
- * uCode).  Bootstrap reloads these runtime images into SRAM, and restarts the

+===============================================================================
+			U S E R  M A N U A L
+
+1) FOR DRIVER INSTALL
+
+	a) Copy sd8787.bin to /lib/firmware/mrvl/ directory,
+	   create the directory if it doesn't exist.
+	b) Install WLAN driver,
+		insmod mwifiex.ko
+	c) Uninstall WLAN driver,
+		ifconfig mlanX down
+		rmmod mwifiex
+
+
+2) FOR DRIVER CONFIGURATION AND INFO
+	The configurations can be done either using the 'iw' user space
+	utility or debugfs.
+
+	a) 'iw' utility commands
+
+	Following are some useful iw commands:-
+
+iw dev mlan0 scan
+
+	This command will trigger a scan.
+	The command will then display the scan table entries
+
+iw dev mlan0 connect -w <SSID> [<freq in MHz>] [<bssid>] [key 0:abcde d:1123456789a]
+	The above command can be used to connect to an AP with a particular SSID.
+	Ap's operating frequency can be specified or even the bssid. If the AP is using
+	WEP encryption, wep keys can be specified in the command.
+	Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user.
+
+iw dev mlan0 disconnect
+	This command will be used to disconnect from an AP.
+
+
+iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde]
+	The command will be used to join or create an ibss. Optionally, operating frequency,
+	bssid and the security related parameters can be specified while joining/creating
+	and ibss.
+
+iw dev mlan0 ibss leave
+	The command will be used to leave an ibss network.
+
+iw dev mlan0 link
+	The command will be used to get the connection status. The command will return parameters
+	such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate.
+
+	Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported.
+
+	b) Debugfs interface
+
+	The debugfs interface can be used for configurations and for getting
+	some useful information from the driver.
+	The section below explains the configurations that can be
+	done.
+
+	Mount debugfs to /debugfs mount point:
+
+		mkdir /debugfs
+		mount -t debugfs debugfs /debugfs
+
+	The information is provided in /debugfs/mwifiex/mlanX/:
+
+iw reg set <country code>
+	The command will be used to change the regulatory domain.
+
+iw reg get
+	The command will be used to get current regulatory domain.
+
+info
+	This command is used to get driver info.
+
+	Usage:
+		cat info
+
+	driver_name = "mwifiex"
+	driver_version = <driver_name, driver_version, (firmware_version)>
+	interface_name = "mlanX"

+	num_rx_pkts_err = <number of Rx packets failed to receive from device>
+	carrier "on" | "off"
+	tx queue "stopped" | "started"
+
+	The following debug info are provided in /debugfs/mwifiex/mlanX/debug:
