From 5d5fb10f9cfe105fd1e160fdfc8bb77bd7492799 Mon Sep 17 00:00:00 2001 From: Mikael Olsson Date: Fri, 12 Feb 2021 17:30:16 +0100 Subject: plat/arm/juno: Add support to use hw_config in BL31 To make it possible to use the hw_config device tree for dynamic configuration in BL31 on the Arm Juno platform. A placeholder hw_config has been added that is included in the FIP and a Juno specific BL31 setup has been added to populate fconf with the hw_config. Juno's BL2 setup has been updated to align it with the new behavior implemented in the Arm FVP platform, where fw_config is passed in arg1 to BL31 instead of soc_fw_config. The BL31 setup is expected to use the fw_config passed in arg1 to find the hw_config.
