-/************************** EEPROM BANDS ****************************
- *
- * The iwl_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl_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.
