-What: AR9170USB
-When: 2.6.40
-
-Why: This driver is deprecated and the firmware is no longer
- maintained. The replacement driver "carl9170" has been
- around for a while, so the devices are still supported.

- This driver is going to get replaced by carl9170.
-
- 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
- * uCode from where it left off before the power-down.
- *
- * NOTE: Initialization uCode does *not* run as part of the save/restore
- * procedure.
- *
- * This save/restore method is mostly for autonomous power management during
- * normal operation (result of POWER_TABLE_CMD). Platform suspend/resume and
- * RFKILL should use complete restarts (with total re-initialization) of uCode,
- * allowing total shutdown (including BSM memory).
- *
- * Note that, during normal operation, the host DRAM that held the initial
- * startup data for the runtime code is now being used as a backup data cache
- * for modified data! If you need to completely re-initialize the NIC, make
- * sure that you use the runtime data image from the uCode distribution file,
- * not the modified/saved runtime data. You may want to store a separate
- * "clean" runtime data image in DRAM to avoid disk reads of distribution file.

+===============================================================================
+ 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:
+

+ <offset>: offset of register
+ [value]: value to be written
+
+ Examples:
+ echo "1 0xa060" > regrdwr : Read the MAC register
+ echo "1 0xa060 0x12" > regrdwr : Write the MAC register
+ echo "1 0xa794 0x80000000" > regrdwr
+ : Write 0x80000000 to MAC register

+ This command is used to read the EEPROM contents of the card.
+
+ Usage:
+ echo "<offset> <length>" > rdeeprom
+ cat rdeeprom
+
+ where the parameters are,
+ <offset>: multiples of 4
+ <length>: 4-20, multiples of 4
+
+ Example:
