We had exit but we didn't have atexit, and we were calling panic and tf_printf from exit, which generated a dependency from exit to them. Having atexit allows to set a different function pointer in every image. Change-Id: I95b9556d680d96249ed3b14da159b6f417da7661 Signed-off-by: Roberto Vargas <roberto.vargas@arm.com>
