From fff2ad9926ca31bff45de06938955e2ace453ab4 Mon Sep 17 00:00:00 2001 From: You-Cheng Syu Date: Tue, 29 Jan 2019 20:04:59 +0800 Subject: google/kukui: Move some initialization from bootblock to verstage MT8183 only allows booting from eMMC, so we have to do eMMC emulation from an external source, for example EC, which makes the size of bootblock very important. This CL moves some initialization steps from bootblock to verstage. This will save us about 2700 bytes (before compression) / 1024 bytes (after LZ4 compression) in bootblock. In case of CONFIG_VBOOT is disabled, these initialization steps will be done in romstage.
