Each implementation requires a set of auto-generated files describing the secure partitions:

* `generate_partition_code.py` - Generate files for both implementations.
* `generate_mbed_spm_partition_code.py` - Generate files for MBED_SPM.

## Secure image generation

`release.py` is the script assigned with compiling the secure images:

```
usage: release.py [-h] [-m MCU] [-d] [--commit]
usage: release.py [-h] [-m MCU] [-d] [-q] [-l] [--commit] [--skip-tests]
[-x ...]

optional arguments:
-h, --help show this help message and exit
-m MCU, --mcu MCU build for the given MCU
-d, --debug set build profile to debug
--commit create a git commit for each platform
-h, --help show this help message and exit
-m MCU, --mcu MCU build for the given MCU
-d, --debug set build profile to debug
-q, --quiet No Build log will be printed
-l, --list Print supported PSA secure targets
--commit create a git commit for each platform
--skip-tests skip the test build phase
-x ..., --extra ... additional build parameters
```

* When `MCU ` is not specified, the script compiles all the images for all the targets.
* When `-d/--debug` is not specified, the script compiles the images using the release profile.
* When `--commit` is not specified, the script will not commit the images to git.
* A user can specify additional commands that will be passed on to the build commands (Ex. -D for compilation defines).

This script should be run in following scenarios:
