ZephyOS support for STM32H757

[SarfarazShaikh-eaton]

I have few queries for zephyOS support for STM32H757

1. Does ZephyOS support symmetric multipoint processing on cortex M7 and M4 cores.
2. Can I only execute ZephyOS on M7 and baremetal application on M4 core.
3. Does ZephyOS support OpenAMP for STM32H757 between cortex M7 and M4
4. If OpenAMP is supported for STM32H757 via ZephyOS , is it possible to communicate between ZephyOS on M7 and baremetal OpenAMP on M4 ?

Regards,
