7  *  e1000_raise_eec_clk - Raise EEPROM clock
9  *  @eecd: pointer to the EEPROM
11  *  Enable/Raise the EEPROM clock bit.
22  *  e1000_lower_eec_clk - Lower EEPROM clock
24  *  @eecd: pointer to the EEPROM
26  *  Clear/Lower the EEPROM clock bit.
37  *  e1000_shift_out_eec_bits - Shift data bits our to the EEPROM
39  *  @data: data to send to the EEPROM
42  *  We need to shift 'count' bits out to the EEPROM.  So, the value in the
43  *  "data" parameter will be shifted out to the EEPROM one bit at a time.
78  *  e1000_shift_in_eec_bits - Shift data bits in from the EEPROM
82  *  In order to read a register from the EEPROM, we need to shift 'count' bits
83  *  in from the EEPROM.  Bits are "shifted in" by raising the clock input to
84  *  the EEPROM (setting the SK bit), and then reading the value of the data out
115  *  e1000e_poll_eerd_eewr_done - Poll for EEPROM read/write completion
117  *  @ee_reg: EEPROM flag for polling
119  *  Polls the EEPROM status bit for either read or write completion based
143  *  e1000e_acquire_nvm - Generic request for access to EEPROM
146  *  Set the EEPROM access request bit and wait for EEPROM access grant bit.
148  *  EEPROM access and return -E1000_ERR_NVM (-1).
177  *  e1000_standby_nvm - Return EEPROM to standby state
180  *  Return the EEPROM to a standby state.
201  *  e1000_stop_nvm - Terminate EEPROM command
204  *  Terminates the current command by inverting the EEPROM's chip select pin.
219  *  e1000e_release_nvm - Release exclusive access to EEPROM
222  *  Stop any current commands to the EEPROM and clear the EEPROM request bit.
236  *  e1000_ready_nvm_eeprom - Prepares EEPROM for read/write
239  *  Setups the EEPROM for reading and writing.
257 		 * The EEPROM will signal that the command has been completed  in e1000_ready_nvm_eeprom()
283  *  e1000e_read_nvm_eerd - Reads EEPROM using EERD register
285  *  @offset: offset of word in the EEPROM to read
287  *  @data: word read from the EEPROM
289  *  Reads a 16 bit word from the EEPROM using the EERD register.
324  *  e1000e_write_nvm_spi - Write to EEPROM using SPI
326  *  @offset: offset within the EEPROM to be written to
328  *  @data: 16 bit word(s) to be written to the EEPROM
330  *  Writes data to EEPROM at offset using SPI interface.
333  *  EEPROM will most likely contain an invalid checksum.
382 		/* Loop to allow for up to whole page write of eeprom */  in e1000e_write_nvm_spi()
408  *  Reads the product board assembly (PBA) number from the EEPROM and stores
514  *  Reads the device MAC address from the EEPROM and stores the value.
515  *  Since devices with two ports use the same EEPROM, we increment the
540  *  e1000e_validate_nvm_checksum_generic - Validate EEPROM checksum
543  *  Calculates the EEPROM checksum by reading/adding each word of the EEPROM
544  *  and then verifies that the sum of the EEPROM is equal to 0xBABA.
570  *  e1000e_update_nvm_checksum_generic - Update EEPROM checksum
573  *  Updates the EEPROM checksum by reading/adding each word of the EEPROM
574  *  up to the checksum.  Then calculates the EEPROM checksum and writes the
575  *  value to the EEPROM.
600  *  e1000e_reload_nvm_generic - Reloads EEPROM
603  *  Reloads the EEPROM by setting the "Reinitialize from EEPROM" bit in the
