  * 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
  *
  * 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.

  * To write eeprom data for a specific offset:
  * 5210 - enable eeprom access (AR5K_PCICFG_EEAE)
  *        write data to AR5K_EEPROM_BASE +(4 * offset)
  *        check the eeprom status register
  * 5211 - write AR5K_EEPROM_CMD_RESET on AR5K_EEPROM_CMD
  * 5212   write offset to AR5K_EEPROM_BASE
  *        write data to data register
  *    write AR5K_EEPROM_CMD_WRITE on AR5K_EEPROM_CMD
  *        check the eeprom status register
  *
  * For more infos check eeprom_* functs and the ar5k.c
  * file posted in madwifi-devel mailing list.
