With CONFIG_USE_IRQ and DEBUG macro defined, display_banner function printed stack address for IRQ and FIQ.
Global variables IRQ_STACK_START and FIQ_STACK_START are set in interrupt_init function. The function display_banner is called from board_init_f, while interrupt_init is called from board_init_r. So, display_banner always resulted in just printing initial values of IRQ_STACK_START and FIQ_STACK_START as follows: IRQ Stack: 0badc0de FIQ Stack: 0badc0de It is almost meaningless information because 0x0badc0de is a hard-coded value in arch/arm/cpu/$(CPU)/start.S. This commit moves the stack info display code after interrupt_init call.
