 * 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

/*
 * EEPROM access registers
 *
 * Here we got a difference between 5210/5211-12
 * read data register for 5210 is at 0x6800 and
 * status register is at 0x6c00. There is also
 * no eeprom command register on 5210 and the
 * offsets are different.
 *
 * 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.
 *
 * To write eeprom data for a specific offset:

/*
 * 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):
