From 4f9753e4808ac33ab19e126585abece718b7c6f8 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Thu, 30 Mar 2023 21:03:32 +0530 Subject: mb/google/rex: Add fmd for debug FSP Debug FSP is ~920KiB larger than release FSP and we don't have sufficient space for rex flash layout. Remove RW_LEGACY and split them into RW_SECTION_A/B so we can have a room for it. Note: This fmd will only used for internal testing/debugging and not for the firmware in released devices. BUG=b:262868089 TEST=Build google/rex with CONFIG_BUILDING_WITH_DEBUG_FSP.
