Makefile中頭文件包含

ccflags-y+=-Werror
ccflags-y+=-I$(M)/include/arm_common
ccflags-y+=-I$(M)/include/linux
ccflags-y+=-I$(M)/include
ccflags-y+=-I$(M)/core

ccflags-y+=-Werror
ccflags-y+=-I$(M)/include/linux
ccflags-y+=-I$(M)/include

上文爲Optee拷貝前的h文件引用路徑，移植到drivers目錄下時，需要更改h文件路徑，所以做如下更改：

ccflags-y+=-Werror
ccflags-y+=-Idrivers/optee/include/arm_common
ccflags-y+=-Idrivers/optee/include/linux
ccflags-y+=-Idrivers/optee/include
ccflags-y+=-Idrivers/optee/core

ccflags-y+=-Werror
ccflags-y+=-Idrivers/optee/include/linux
ccflags-y+=-Idrivers/optee/include
