Function Documentation

void spm_hal_mailbox_notify ( void )

Notify the peer processor about a general event occurrence.

Wake up the peer processor waiting on the mailbox driver event.

Note: Implement the functions below with target-specific code.

void spm_hal_memory_protection_init ( void )

Configure memory protection mechanism.

Apply memory protection schemes to ensure secure memory can only be accessed from secure-state.

Note: The function must be implemented by target specific code.

void spm_hal_start_nspe ( void )

Start running the NSPE.

Secure Processing Environment (SPE) expected to boot first. Once all the initializations are done, Nonsecure Processing Environment (NSPE) should be booted.

Note: The function must be implemented by target specific code.

void spm_mailbox_irq_callback ( void )

Wakeup mailbox dispatcher thread.

Arm implements this function, which is expected to be called by target- specific Inter-Processor-Communication logic on mailbox interrupt handler.
