From 33180dfb39603f6329a35264b85a4582059e394e Mon Sep 17 00:00:00 2001 From: Ed Swierk Date: Fri, 5 Dec 2014 22:56:13 +0000 Subject: Add support for Intel 82599 10 GbE NICs The Intel 82599 series of 10 GbE controllers has a bit-banged SPI interface that's register-compatible with the one in the 1 GbE controllers, except the register addresses are shifted up by 0x10000, cf. Intel document 331520: http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/82599-10-gbe-controller-datasheet.pdf This patch was tested with a board that has the 0x10fc device and a Micron M25P40 SPI flash chip. The PCI IDs and names for the devices are per Intel document 331521 https://www-ssl.intel.com/content/dam/www/public/us/en/documents/specification-updates/82599-10-gbe-controller-spec-update.pdf and the PCI SIG device ID registry with small refinements. Corresponding to flashrom svn r1856.
