/************************** 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.
