There is no need to call rwb->rhreloade() when nblocks is 0,
and some platform(eg: BES) has the limit that the parameter
of len in pltatform flash read function cant't be 0.
issue:
in rwb_wrflush():
memmove(rwb->wrbuffer + padblocks * rwb->blocksize,
rwb->wrbuffer, rwb->wrnblocks * rwb->blocksize);
when the offest from rwb->wrblockstart to startblock plus rwb->wrnblocks is greater
than rwb->wralignblocks, it will be causing memory overflow since rwb->wrbuffer is
allocated rwb.wrmaxblock(rwb.wralignblocks) blocks.
fix:
Let us ensure that the wrblockstart in rwbuffer must be aligned according to
wralignblocks after writing, so there is no need to perform memmove when flushing

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

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done
