/*
 * 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.

 * As i can see in ar5k_ar5210_tx_start Reyk uses some of the values of BCR

 * here and SNP/SNAP means "snapshot" (so this register gets synced with BCR).
 * So SNAPPEDBCRVALID sould also stand for "snapped BCR -values- valid", so i
 * renamed it to SNAPSHOTSVALID to make more sense. I realy have no idea what
 * else can it be. I also renamed SNPBCMD to SNPADHOC to match BCR.

 * a retry limit register (0x1080 - 0x10ac), a channel time register
 * (0x10c0 - 0x10ec), a misc-settings register (0x1100 - 0x112c) and
 * a sequence number register (0x1140 - 0x116c). It seems that "global"
 * registers here afect all queues (see use of DCU_GBL_IFS_SLOT in ar5k).
 * We use the same macros here for easier register access.

 * To read eeprom data for a specific offset:
 * 5210 - enable eeprom access (AR5K_PCICFG_EEAE)
 *        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.

/*
 * RF Buffer register
 *
 * There are some special control registers on the RF chip
 * that hold various operation settings related mostly to
 * the analog parts (channel, gain adjustment etc).
 *
 * We don't write on those registers directly but
 * we send a data packet on the buffer register and
 * then write on another special register to notify hw
 * to apply the settings. This is done so that control registers
 * can be dynamicaly programmed during operation and the settings
 * are applied faster on the hw.
 *
 * We sent such data packets during rf initialization and channel change
 * through ath5k_hw_rf*_rfregs and ath5k_hw_rf*_channel functions.
 *
 * The data packets we send during initializadion are inside ath5k_ini_rf
 * struct (see ath5k_hw.h) and each one is related to an "rf register bank".
 * We use *rfregs functions to modify them  acording to current operation
 * mode and eeprom values and pass them all together to the chip.
 *
 * It's obvious from the code that 0x989c is the buffer register but
 * for the other special registers that we write to after sending each
 * packet, i have no idea. So i'll name them BUFFER_CONTROL_X registers
 * for now. It's interesting that they are also used for some other operations.
 *
 * Also check out hw.h and U.S. Patent 6677779 B1 (about buffer
 * registers and control registers):
