Revert "Remove FSP Rangeley SOC and mohonpeak board support"
This chip is still being used and should not have been deleted. It's a current intel chip, and doesn't even require an ME binary. This reverts commit 959478a763c16688d43752adbae2c76e7764da45. Change-Id: I78594871f87af6e882a245077b59727e15f8021a Signed-off-by: Martin Roth <martinroth@google.com> Reviewed-on: http://review.coreboot.org/11860 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marc@marcjonesconsulting.com> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
