准备stm32mp-ddr-phy
参考stm32mp-ddr-phy-A2022.11-r0目录下README.HOW_TO.txt.stm32mp2，非常重要！！！
cd ~/develop/STM32MP2/test/stm32mp-openstlinux-6.6-yocto-scarthgap-mpu-v25.08.27/sources/ostl-linux
#准备stm32mp-ddr-phy源码
cd stm32mp-ddr-phy-A2022.11-r0/
tar xf stm32mp-ddr-phy-A2022.11-r0.tar.xz
cd stm32mp-ddr-phy-A2022.11/
test -d .git || git init . && git add . && git commit -m "new stm32mp-ddr-phy" && git gc
git checkout -b WORKING准备TF-A
参考tf-a-stm32mp-v2.10.13-stm32mp-r2-r0目录下README.HOW_TO.txt.stm32mp2，非常重要！！！
cd tf-a-stm32mp-v2.10.13-stm32mp-r2-r0/
vi test.sh
#在test.sh增加以下内容，参考README.HOW_TO.txt.stm32mp2的4.2，打补丁+git管理

make -f $PWD/../Makefile.sdk.stm32mp2 clean
make -f $PWD/../Makefile.sdk.stm32mp2 stm32按照步骤，编译成功如下图所示，同时会在arm-trusted-firmware目录下生成多个文件和目录
准备optee
参考optee-os-stm32mp-4.0.0-stm32mp-r2-r0目录下README.HOW_TO.txt.stm32mp2，非常重要！！！
！！！注意：如果是在当前的shell环境下面，则不需要重新声明TF-A的环境变量

准备u-boot
参考u-boot-stm32mp-v2023.10-stm32mp-r2-r0目录下README.HOW_TO.txt.stm32mp2，非常重要！！！
！！！注意：如果是在当前的shell环境下面，则不需要重新声明TF-A的环境变量
