Overview
This sample is based on R-Car S4 SDK v3.16.0.
SCP sample application consists of Linux on CA55, SCP sample application on CR52 and SCP sample application on G4MH and they can communicate with SCMI.
You need to rebuild Linux Image, dtb, ICUMX firmware and Security BSP for SCP.
SCP sample application on CR52 and G4MH is built on MCAL build tree. You need to install SCP code on MCAL build tree and to edit MCAL build systems to build SCP module.
SCP module needs MCAL MCU library. You must build MCAL MCU module before building SCP sample application.
Prepare the environments

Build and Execute SCP sample application
1. How to build SCP on G4MH
(here, git bash is used.)
# Step 1. Install SCP code
# Unzip SCP source tree on MCAL source tree.
