RTEMS -initialization is complete, interrupts and tasking are enabled, -and the device drivers are initialized. This field may be NULL -to indicate that the hook is not utilized. - -@item idle_task -is the address of the optional user -provided routine which is used as the system's IDLE task.

This field may be NULL to indicate that the default IDLE -is to be used. - -@item do_zero_of_workspace -indicates whether RTEMS should -zero the Workspace as part of its initialization. If set to -TRUE, the Workspace is zeroed. Otherwise, it is not. - -@item idle_task_stack_size -is the size of the RTEMS idle task stack in bytes. -If this number is less than MINIMUM_STACK_SIZE, then the -idle task's stack will be MINIMUM_STACK_SIZE in byte. - -@item interrupt_stack_size -is the size of the RTEMS allocated interrupt stack in bytes. -This value must be at least as large as MINIMUM_STACK_SIZE. - -@item extra_mpci_receive_server_stack -is the extra stack space allocated for the RTEMS MPCI receive server task -in bytes. The MPCI receive server may invoke nearly all directives and -may require extra stack space on some targets. - -@item stack_allocate_hook -is the address of the optional user provided routine which allocates -memory for task stacks. If this hook is not NULL, then a stack_free_hook -must be provided as well. - -@item stack_free_hook -is the address of the optional user provided routine which frees -memory for task stacks.
