### TF-M SPM porting (for ARMv8-M targets)

TF-M HAL functions are defined in `tfm_spm_hal.h`.
The `tfm_spm_hal.h` file defines TF-M HAL functions.

Mbed OS integrates TF-M sources from [trusted-firmware-m.git](https://git.trustedfirmware.org/trusted-firmware-m.git/about/).

For more information about Mbed OS builds and related concepts, please see [Mbed OS build rules](../reference/mbed-os-build-rules.html).
