The driver's main purpose is to support the porting of the open source component optee_client (https://github.com/OP-TEE/optee_client) to nttux. The basic function of the driver module is to convert the REE application layer data and send it to the TEE through rpmsg. The main functions include 1 driver registration. we need to register a device driver(/dev/tee0) through optee_register function. 2 open the driver 3 ioctl the driver The ioctl command passes different parameters and commands, and interacts with the TEE through rpmsg. 4 close the driver Signed-off-by: hujun5 <hujun5@xiaomi.com>

* drivers_initialize will be called once during OS initialization after
|
|
* the basic OS services have been initialized.
|
|
*
|
|
* drivers_initialize is called after the OS initialized but before the
|
|
* user initialization logic has been started and before the libraries
|
|
* have been initialized. OS services and driver services are available.
