From 564e073cd5538a1e565fb55a6bc0a934107f5f15 Mon Sep 17 00:00:00 2001 From: Chia-Wei Wang Date: Wed, 27 Sep 2023 13:51:04 +0800 Subject: refactor(ast2700): adopt RESET_TO_BL31 boot flow Revise the AST2700 boot flow to the RESET_TO_BL31 scheme. The execution of BL1/2 can be saved from ARM CA35 while most low level platform initialization are moved to a preceding MCU. This patch updates the build configuration and also adds the SMP mailbox setup code to hold secondary cores until they are being waken up.
