作业tf

先解压源代码

tar -xvf tf-a-stm32mp-2.2.r2-r0.tar.gz

在源码上打补丁

for p in `ls -1 ../*.patch`; do patch -p1 < $p; done

配置交叉编译链

复制复制设备树

到fdts

cp fdts/stm32mp15xx-dkx.dtsi fdts/stm32mp15xx-fsmp1x.dtsi
cp fdts/stm32mp157a-dk1.dts fdts/stm32mp157a-fsmp1a.dts

修改再在顶层目录下修改Makefile.sdk中的TFA_DEVICETREE配置项，加上 stm32mp157a-fsmp1a

 然后没了

错误了
