Add new programmer for SPI EEPROMs attached to Intel 82580 NICs
This patch lets you read and write the EEPROM on 82580-based gigabit NIC
cards. So far it has been tested on copper NICs only, but other variants
employing this controller should work too.
It is a nice substitution for the official eeupdate tool.
Speed is quite decent: less than 4 seconds for erases or writes of 32 kB.
Corresponding to flashrom svn r1832.

+.BR "nicintel_eeprom " programmer
+This is the first programmer module in flashrom that does not provide access to NOR flash chips but EEPROMs
+mounted on gigabit Ethernet cards based on Intel's 82580 NIC. Because EEPROMs normally do not announce their
+size nor allow to be identified, the controller relies on correct size values written to predefined addresses
+within the chip. Flashrom follows this scheme but assumes the minimum size of 16 kB (128 kb) if an unprogrammed
+EEPROM/card is detected. Intel specifies following EEPROMs to be compatible: Atmel AT25128, AT25256, Micron (ST)
+M95128, M95256 and OnSemi (Catalyst) CAT25CS128.
