I've found it helpful to try to maintain an ordered list in bspstart.c
of what gets init'd when, especially since some of the interesting stuff
(in our case at least) gets run from various rtems hooks (eg: postdriver).

This is an abbreviated version of startup ordering.

 *      clear bss
 *  
 *      bsp_start()
 *          floss_interrupt_init()

 *          bsp_write_protect_code()

                    ...
 *              (*cpu_table->pretasking_hook)();
