11  *  igb_raise_eec_clk - Raise EEPROM clock
13  *  @eecd: pointer to the EEPROM
15  *  Enable/Raise the EEPROM clock bit.
26  *  igb_lower_eec_clk - Lower EEPROM clock
28  *  @eecd: pointer to the EEPROM
30  *  Clear/Lower the EEPROM clock bit.
41  *  igb_shift_out_eec_bits - Shift data bits our to the EEPROM
43  *  @data: data to send to the EEPROM
46  *  We need to shift 'count' bits out to the EEPROM.  So, the value in the
47  *  "data" parameter will be shifted out to the EEPROM one bit at a time.
82  *  igb_shift_in_eec_bits - Shift data bits in from the EEPROM
86  *  In order to read a register from the EEPROM, we need to shift 'count' bits
87  *  in from the EEPROM.  Bits are "shifted in" by raising the clock input to
88  *  the EEPROM (setting the SK bit), and then reading the value of the data out
120  *  igb_poll_eerd_eewr_done - Poll for EEPROM read/write completion
122  *  @ee_reg: EEPROM flag for polling
124  *  Polls the EEPROM status bit for either read or write completion based
151  *  igb_acquire_nvm - Generic request for access to EEPROM
154  *  Set the EEPROM access request bit and wait for EEPROM access grant bit.
156  *  EEPROM access and return -E1000_ERR_NVM (-1).
187  *  igb_standby_nvm - Return EEPROM to standby state
190  *  Return the EEPROM to a standby state.
211  *  e1000_stop_nvm - Terminate EEPROM command
214  *  Terminates the current command by inverting the EEPROM's chip select pin.
229  *  igb_release_nvm - Release exclusive access to EEPROM
232  *  Stop any current commands to the EEPROM and clear the EEPROM request bit.
246  *  igb_ready_nvm_eeprom - Prepares EEPROM for read/write
249  *  Setups the EEPROM for reading and writing.
269 		 * The EEPROM will signal that the command has been completed  in igb_ready_nvm_eeprom()
297  *  igb_read_nvm_spi - Read EEPROM's using SPI
299  *  @offset: offset of word in the EEPROM to read
301  *  @data: word read from the EEPROM
303  *  Reads a 16 bit word from the EEPROM.
357  *  igb_read_nvm_eerd - Reads EEPROM using EERD register
359  *  @offset: offset of word in the EEPROM to read
361  *  @data: word read from the EEPROM
363  *  Reads a 16 bit word from the EEPROM using the EERD register.
399  *  igb_write_nvm_spi - Write to EEPROM using SPI
401  *  @offset: offset within the EEPROM to be written to
403  *  @data: 16 bit word(s) to be written to the EEPROM
405  *  Writes data to EEPROM at offset using SPI interface.
408  *  EEPROM will most likley contain an invalid checksum.
457 		/* Loop to allow for up to whole page write of eeprom */  in igb_write_nvm_spi()
483  *  Reads the product board assembly (PBA) number from the EEPROM and stores
592  *  Reads the device MAC address from the EEPROM and stores the value.
593  *  Since devices with two ports use the same EEPROM, we increment the
618  *  igb_validate_nvm_checksum - Validate EEPROM checksum
621  *  Calculates the EEPROM checksum by reading/adding each word of the EEPROM
622  *  and then verifies that the sum of the EEPROM is equal to 0xBABA.
650  *  igb_update_nvm_checksum - Update EEPROM checksum
653  *  Updates the EEPROM checksum by reading/adding each word of the EEPROM
654  *  up to the checksum.  Then calculates the EEPROM checksum and writes the
655  *  value to the EEPROM.
