-/*************** DMA-QUEUE-GENERAL-FUNCTIONS *****
- * DMA services
- *
- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill. Driver and device exchange status of each
- * queue via "read" and "write" pointers. Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels. Each queue is mapped to a single DMA channel.
- *
- * For Tx queue, there are low mark and high mark limits. If, after queuing
- * the packet for Tx, free space become < low mark, Tx queue stopped. When
- * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
- * Tx queue resumed.
- *
- * The 3945 operates with six queues: One receive queue, one transmit queue
- * (#4) for sending commands to the device firmware, and four transmit queues
- * (#0-3) for data tx via EDCA. An additional 2 HCCA queues are unused.

-/************************** EEPROM BANDS ****************************
- *
- * The iwl3945_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl3945_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel. We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware. This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel. There is no corresponding channel information for that
- * entry.

- * When initializing the NIC, the host driver points the BSM to the
- * "initialize" uCode image. This uCode sets up some internal data, then
- * notifies host via "initialize alive" that it is complete.
- *
- * The host then replaces the BSM_DRAM_* pointer values to point to the
- * normal runtime uCode instructions and a backup uCode data cache buffer
- * (filled initially with starting data values for the on-board processor),
- * then triggers the "initialize" uCode to load and launch the runtime uCode,
- * which begins normal operation.
- *
- * When doing a power-save shutdown, runtime uCode saves data SRAM into
- * the backup data cache in DRAM before SRAM is powered down.
- *
- * When powering back up, the BSM loads the bootstrap program. This reloads
- * the runtime uCode instructions and the backup data cache into SRAM,
