/*
 * Register values for Atheros 5210/5211/5212 cards from OpenBSD's ar5k
 * maintained by Reyk Floeter
 *
 * I tried to document those registers by looking at ar5k code, some
 * 802.11 (802.11e mostly) papers and by reading various public available
 * Atheros presentations and papers like these:
 *
 * 5210 - http://nova.stanford.edu/~bbaas/ps/isscc2002_slides.pdf
 *        http://www.it.iitb.ac.in/~janak/wifire/01222734.pdf
 *
 * 5211 - http://www.hotchips.org/archives/hc14/3_Tue/16_mcfarland.pdf
 *
 * This file also contains register values found on a memory dump of
 * Atheros's ART program (Atheros Radio Test), on ath9k, on legacy-hal
 * released by Atheros and on various debug messages found on the net.

 * renamed it to SNAPSHOTSVALID to make more sense. I realy have no idea what

 *        read AR5K_EEPROM_BASE +(4 * offset)
 *        check the eeprom status register
 *        and read eeprom data register.
 *
 * 5211 - write offset to AR5K_EEPROM_BASE
 * 5212   write AR5K_EEPROM_CMD_READ on AR5K_EEPROM_CMD
 *        check the eeprom status register
 *        and read eeprom data register.
