Secure boot solution for STM32U5 on Zephyr

[HDot]

Did you come to a conclusion on this approach? I am having the exact same dilemma.

There is an approach to do it through TF-M, but then how is the support from ST on that part? 
https://github.com/zephyrproject-rtos/trusted-firmware-m/tree/release/2.2.x

Again, I want to emphasize on what is available from ST and not compare it to nRF. This way I can decide which approach to take for the secure boot solution on STM32U5.
