commit 6faa9c8bcfa70d308fd1462c87fe73b6093a7657 Author: Stefan Reinauer stefan.reinauer@coreboot.org Date: Sun Apr 24 11:26:37 2016 -0700
vendorcode/intel: Move FSP code out of drivers and into vendorcode
Intel's vendorcode, despite not being a driver, was originally committed into drivers. In order to keep FSP code from being spread all across the code base, move the common FSP code from src/drivers/fsp<version>/ over into the vendor code at src/vendorcode/intel/fsp/fsp<version>/common.
This also fixes an outstanding issue where Intel's FSP Kconfig options started showing up twice, once in the SOC sub menu (where they belong), and once under the drivers sub menu.
