/*
 * EEPROM defines for Version 1 Crete EEPROM.
 *
 * The EEPROM is segmented into three sections:
 *
 *    PCI/Cardbus default configuration settings
 *    Cardbus CIS tuples and vendor-specific data
 *    Atheros-specific data
 *
 * EEPROM entries are read 32-bits at a time through the PCI bus
 * interface but are all 16-bit values.
 *
 * Access to the Atheros-specific data is controlled by protection
 * bits and the data is checksum'd.  The driver reads the Atheros
 * data from the EEPROM at attach and caches it in its private state.
 * This data includes the local regulatory domain, channel calibration
 * settings, and phy-related configuration settings.
