 * CSR (control and status registers)
 *
 * CSR registers are mapped directly into PCI bus space, and are accessible
 * whenever platform supplies power to device, even when device is in
 * low power states due to driver-invoked device resets
 * (e.g. IWM_CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes.
 *
 * Use iwl_write32() and iwl_read32() family to access these registers;
 * these provide simple PCI bus access, without waking up the MAC.
 * Do not use iwl_write_direct32() family for these registers;
 * no need to "grab nic access" via IWM_CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ.
 * The MAC (uCode processor, etc.) does not need to be powered up for accessing
 * the CSR registers.
 *
 * NOTE:  Device does need to be awake in order to read this memory
 *        via IWM_CSR_EEPROM and IWM_CSR_OTP registers

 *         Host sets this during RF KILL power-down sequence (HW, SW, CT KILL)
 *         to release uCode to clear all Tx and command queues, enter
 *         unassociated mode, and power down.
 *         NOTE:  Some devices also use HBUS_TARG_MBX_C register for this bit.
 *     1:  SW_BIT_RFKILL
 *         Host sets this when issuing CARD_STATE command to request
 *         device sleep.
 *     0:  MAC_SLEEP
 *         uCode sets this when preparing a power-saving power-down.
 *         uCode resets this when power-up is complete and SRAM is sane.
 *         NOTE:  device saves internal SRAM data to host when powering down,
 *                and must restore this data after powering back up.
 *                MAC_SLEEP is the best indication that restore is complete.
 *                Later devices (5xxx/6xxx/1xxx) use non-volatile SRAM, and
 *                do not need to save/restore it.

/**
 * 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 5000 series and up, they are used differently
 * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.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 -- unused
 * 5 -- unused
 * 6 -- unused
 * 7 -- Commands
 *
 * 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) window 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 window, 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
 *     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 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!):

/**
 * Rx SRAM Control and Status Registers (RSCSR)
 *
 * These registers provide handshake between driver and device for the Rx queue
 * (this queue handles *all* command responses, notifications, Rx data, etc.
 * sent from uCode to host driver).  Unlike Tx, there is only one Rx
 * queue, and only one Rx DMA/FIFO channel.  Also unlike Tx, which can
 * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
 * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
 * mapping between RBDs and RBs.
 *
 * Driver must allocate host DRAM memory for the following, and set the
 * physical address of each into device registers:
 *
 * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
 *     entries (although any power of 2, up to 4096, is selectable by driver).
 *     Each entry (1 dword) points to a receive buffer (RB) of consistent size
 *     (typically 4K, although 8K or 16K are also selectable by driver).
 *     Driver sets up RB size and number of RBDs in the CB via Rx config
 *     register IWM_FH_MEM_RCSR_CHNL0_CONFIG_REG.
 *
 *     Bit fields within one RBD:
 *     27-0:  Receive Buffer physical address bits [35:8], 256-byte aligned
 *
 *     Driver sets physical address [35:8] of base of RBD circular buffer
 *     into IWM_FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
 *
 * 2)  Rx status buffer, 8 bytes, in which uCode indicates which Rx Buffers
 *     (RBs) have been filled, via a "write pointer", actually the index of
 *     the RB's corresponding RBD within the circular buffer.  Driver sets
 *     physical address [35:4] into IWM_FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
 *
 *     Bit fields in lower dword of Rx status buffer (upper dword not used
 *     by driver:
 *     31-12:  Not used by driver
 *     11- 0:  Index of last filled Rx buffer descriptor
 *             (device writes, driver reads this value)
 *
 * As the driver prepares Receive Buffers (RBs) for device to fill, driver must
 * enter pointers to these RBs into contiguous RBD circular buffer entries,
 * and update the device's "write" index register,
 * IWM_FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
 *
 * This "write" index corresponds to the *next* RBD that the driver will make
 * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
 * the circular buffer.  This value should initially be 0 (before preparing any
 * RBs), should be 8 after preparing the first 8 RBs (for example), and must
 * wrap back to 0 at the end of the circular buffer (but don't wrap before
 * "read" index has advanced past 1!  See below).
 * NOTE:  DEVICE EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
 *
 * As the device fills RBs (referenced from contiguous RBDs within the circular
 * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
 * to tell the driver the index of the latest filled RBD.  The driver must
 * read this "read" index from DRAM after receiving an Rx interrupt from device
 *
 * The driver must also internally keep track of a third index, which is the
 * next RBD to process.  When receiving an Rx interrupt, driver should process
 * all filled but unprocessed RBs up to, but not including, the RB
 * corresponding to the "read" index.  For example, if "read" index becomes "1",
 * driver may process the RB pointed to by RBD 0.  Depending on volume of
 * traffic, there may be many RBs to process.
 *
 * If read index == write index, device thinks there is no room to put new data.
 * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
 * be safe, make sure that there is a gap of at least 2 RBDs between "write"
 * and "read" indexes; that is, make sure that there are no more than 254
 * buffers waiting to be filled.
