Program execution flow

The flow of program execution is shown below:

  secureStart     startup_secure.s: Initialization of Secure world
       |
    __main        ARM library initialization
       |
     main         main_secure.c: Enable caches and configure TZPC
       |
  monitorInit     monitor.s: initialize Monitor
       |
     main         main_secure.c: Print message and execute SMC
       |
     S -> NS
       |
  normalStart     startup_normal.s: Initialization of Normal world
       |
    __main        ARM library initialization
       |
     main         main_normal.c: Enable caches, print message and execute SMC
       |
    NS -> S
       |
  SMC_Handler     monitor.s: Perform context switch from NS to S
       |
     main         main_secure.c: Print message and execute SMC
       |
  SMC_Handler     monitor.s: Perform context switch from S to NS
       |
     S -> NS
       |
     main         main_normal.c: Print message and execute SMC
       |
    NS -> S
       |
  SMC_Handler     monitor.s: Perform context switch from NS to S
       |
     main         main_secure.c: Print message and execute SMC
