  /**
   * 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 il_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 il_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 C_POWER_TBL).  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.

  /**
   * Tx Scheduler
   *
   * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
   * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
   * host DRAM.  It steers each frame's Tx command (which contains the frame
   * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
   * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
   * but one DMA channel may take input from several queues.
   *
   * Tx DMA FIFOs have dedicated purposes.  For 4965, they are used as follows
   * (cf. default_queue_to_tx_fifo in 4965.c):
   *
   * 0 -- EDCA BK (background) frames, lowest priority
   * 1 -- EDCA BE (best effort) frames, normal priority
   * 2 -- EDCA VI (video) frames, higher priority
   * 3 -- EDCA VO (voice) and management frames, highest priority
   * 4 -- Commands (e.g. RXON, etc.)
   * 5 -- unused (HCCA)
   * 6 -- unused (HCCA)
   * 7 -- not used by driver (device-internal only)
   *
   *
   * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
   * In addition, driver can map the remaining queues to Tx DMA/FIFO
   * channels 0-3 to support 11n aggregation via EDCA DMA channels.
   *
   * The driver sets up each queue to work in one of two modes:
   *
   * 1)  Scheduler-Ack, in which the scheduler automatically supports a
   *     block-ack (BA) win of up to 64 TFDs.  In this mode, each queue
   *     contains TFDs for a unique combination of Recipient Address (RA)
   *     and Traffic Identifier (TID), that is, traffic of a given
   *     Quality-Of-Service (QOS) priority, destined for a single station.
   *
   *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
   *     each frame within the BA win, including whether it's been transmitted,
   *     and whether it's been acknowledged by the receiving station.  The device
   *     automatically processes block-acks received from the receiving STA,
   *     and reschedules un-acked frames to be retransmitted (successful
   *     Tx completion may end up being out-of-order).
   *
   *     The driver must maintain the queue's Byte Count table in host DRAM
   *     (struct il4965_sched_queue_byte_cnt_tbl) for this mode.
   *     This mode does not support fragmentation.
   *
   * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
   *     The device may automatically retry Tx, but will retry only one frame
   *     at a time, until receiving ACK from receiving station, or reaching
   *     retry limit and giving up.
   *
   *     The command queue (#4/#9) must use this mode!
   *     This mode does not require use of the Byte Count table in host DRAM.
   *
   * Driver controls scheduler operation via 3 means:
   * 1)  Scheduler registers
   * 2)  Shared scheduler data base in internal 4956 SRAM
   * 3)  Shared data in host DRAM
   *
   * Initialization:
   *
   * When loading, driver should allocate memory for:
   * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
   * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
   *     (1024 bytes for each queue).
   *
   * After receiving "Alive" response from uCode, driver must initialize
   * the scheduler (especially for queue #4/#9, the command queue, otherwise
   * the driver can't issue commands!):
   */
  
  /**
   * Max Tx win size is the max number of contiguous TFDs that the scheduler
   * can keep track of at one time when creating block-ack chains of frames.
