/**
* 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
