The HAL functions for PSA SPM.
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.
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.
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.
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.
