@ -35,17 +35,6 @@ Who: Luis R. Rodriguez <lrodriguez@atheros.com>
---------------------------
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Why: This driver is deprecated and the firmware is no longer
maintained.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.

select FW_LOADER
help
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:
http://wireless.kernel.org/en/users/Drivers/ar9170
If you choose to build a module, it'll be called ar9170usb.

*
* A double __ prefix before an access function means that state is checked
* and the current line number and caller function name are printed in addition
* to any other debug output.
*
* The non-prefixed name is the #define that maps the caller into a
* #define that provides the caller's name and __LINE__ to the double
* prefix version.
*
* If you wish to call the function without any debug or state checking,
* you should use the single _ prefix version (as is used by dependent IO
* routines, for example _iwl_read_direct32 calls the non-check version of
* _iwl_read32.)
*
* These declarations are *extremely* useful in quickly isolating code deltas
* which result in misconfiguration of the hardware I/O. In combination with
* git-bisect and the IO debug level you can quickly determine the specific
* commit which breaks the IO sequence to the hardware.

* 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.
