commit 3c6e16fb8fb13d9e4bd2dd1d36bfba565b7f7683 Author: Martin Roth gaumless@gmail.com Date: Sat Jun 20 16:17:12 2015 -0600
southbridge/intel: Create common IFD Kconfig and Makefile
We've got a lot of duplicated code to set up the IFD/ME/TXE/GBE/ETC. This is the start of creating a common interface for all of them.
This also allows us to reduce the chipset dependencies for CBFS_SIZE.
