support for the Hardware Crypto Accelerator on the STM32H753

[aniruddhanalgirkar-eaton]

Is your feature request related to a problem? Please describe.

Hi team,

I'm looking for information regarding support for the Hardware Crypto Accelerator on the STM32H753 when using the TF-M module.

Currently, I see support available for the following boards:

b_u585i_iot02a
nucleo_l552ze_q
stm32h573i_dk
stm32l562e_dk
However, I couldn't find similar support for the NUCLEO-STM32H753ZI.
Is this board on your roadmap for TF-M crypto accelerator support?

If not, could you please advise on how I might enable this functionality?
Would using the STM32 HAL directly be a viable approach, or is there another recommended solution?

Reference: #93520

Thanks in advance!

Describe the solution you'd like

Currently, I see support available for the following boards:
b_u585i_iot02a
nucleo_l552ze_q
stm32h573i_dk
stm32l562e_dk

in the same way there must be Nucleo_h753zi

Describe alternatives you've considered

Can it be worked out by using HAL crypto files? However, if this support for H753 is in roadmap then I can rely on it instead of trying other alternatives like using the HAL, etc.

Since there is no TrustZone component on H7 (CM7 based and not CM33/55/85/..), it won't be supported in Trusted-Firmware M.

okay, so, how can I achieve Hardware Acceleration on this STM32H753? any suggestions plz.

Which crypto do you need ?
There are crypto drivers available in Zephyr directly

Have a look into this implementation

I never worked with it or such implementation before but maybe it helps you
