Hi all,

I’m been working to unify the HAL APIs for IPC Model.

The IPC Model currently uses two different sets of HAL APIs:

• tfm_spm_hal_* - This is mainly used by the Library Model and IPC Model re-uses some of them
• tfm_hal_* - This is introduced for IPC Model and some are shared to Library Model

This might be confusing for platform vendors.

So I’m trying to make it clear for IPC Model by:

• Duplicating the shared APIs and rename the IPC copy to tfm_hal_*
• Combining several platform init APIs to a single tfm_platform_init for IPC Model
• tfm_spm_hal_enable_fault_handlers
• tfm_spm_hal_system_reset_cfg
• tfm_spm_hal_init_debug
• tfm_spm_hal_nvic_interrupt_target_state_cfg
• tfm_spm_hal_nvic_interrupt_enable

With these changes, IPC Model will use tfm_hal_* APIs only.

Please platform owners review these patches to see if any mistakes (the patches mainly move codes around) or any platforms missed in the patches.

Plan to have them merged before the end of October. Thanks.

Best Regards,

Kevin
