broadwell: Preparations for building
Updated Intel Broadwell for differences in the source based on the chromium tree. It is missing most of the recent updates on coreboot.org. - makefile changes for Elog and IDF tool - kconfig changes for ME, ucode, and other updates - update oprom flag - update timestamp mechanism - cbfs payload function is now generic Change-Id: I82bd0792e9dcf81085246873164de6600528d6fe Signed-off-by: Marc Jones <marc.jones@se-eng.com> Reviewed-on: http://review.coreboot.org/7939 Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks <dhendrix@chromium.org>
