Hello build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/21430 to look at the new patch set (#2). Change subject: nicintel_spi: Support for I210/I211 cards ...................................................................... nicintel_spi: Support for I210/I211 cards Implements I210 "raw" flash access as detailed in: http://www.intel.com/content/www/us/en/embedded/products/networking/i210-et… Unfortunately, most of the time the card is in Secure Mode, which means that the raw access is not available. But his should be pretty useful for bringing up boards.

( https://review.coreboot.org/21431 Change subject: nicintel_eeprom: Support for I210 emulated EEprom ...................................................................... nicintel_eeprom: Support for I210 emulated EEprom On the I210 family there is no MAC EEprom, instead there is a big flash (typically around 16Mb) with contents of the old MAC plus other stuff. There is an interface to program the whole flash, but once it is programmed it enters a "Secure Mode" that disables the interface. Luckily, the section with the MAC can still be updated via the EEprom interface.

( https://review.coreboot.org/21430 Change subject: nicintel_spi: Support for I210/I211 cards ...................................................................... nicintel_spi: Support for I210/I211 cards Implements I210 "raw" flash access as detailed in: http://www.intel.com/content/www/us/en/embedded/products/networking/i210-et… Unfortunately, most of the time the card is in Secure Mode, which means that the raw access is not available. But his should be pretty useful for bringing up boards.
