From 6ecd4c65e7d64ad6ed6d4f680b22d12413ea01ae Mon Sep 17 00:00:00 2001 From: Jamie Ryu Date: Wed, 14 Oct 2020 14:21:37 -0700 Subject: mb/google/volteer: Update flashmap descriptor to add ME_RW_A/B region The current CSE firmware update implementation adds CSE RW binary to FW_MAIN_A/B and this increases the boot time due to the size increase of these regions leading to higher loading and hashing time. To mitigate this issue, CSE RW binary is moved from FW_MAIN_A/B to new region, ME_RW_A/B under RW_SECTON_A/B, and this updates the flashmap to add ME_RW_A/B region for CSE RW binary. BUG=b:169077783 TEST=build with cse rw binary, flash and verify volteer2 boots to OS. Verify me_rw binary is added to ME_RW_A/B region.
