From 7bab4c90a72a0e3599d6dbda0a72e8d470fd3fbf Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Thu, 30 Apr 2020 10:34:37 -0500 Subject: mb/google/reef: add default non-ChromeOS FMAP Add a FMAP which supports SMMSTORE and non-ChromeOS payloads, since Apollo Lake-based devices like Reef cannot use an automatically-generated FMAP due to strict layout requirements.
